What is the SI unit of force?
Pascal
Watt
Joule
Newton
The Newton is the SI unit of force because it directly relates to mass and acceleration as defined by Newton's second law. The other units represent different physical quantities, such as energy, power, or pressure.
Which equation represents Newton's Second Law of Motion?
F = a / m
F = m / a
F = m + a
F = m Ă - a
Newton's Second Law of Motion states that force equals mass multiplied by acceleration (F = m Ă - a). This equation clearly defines the relationship between force, mass, and acceleration, unlike the other options which are mathematically incorrect.
On which factors does kinetic energy depend?
Force and acceleration
Velocity and time
Mass and height
Mass and velocity
Kinetic energy is given by the formula ½mv², meaning it depends on both the mass of the object and the square of its velocity. The other options involve factors not directly related to kinetic energy.
What is the definition of work in physics?
Distance traveled by an object
Force applied over a distance
Energy transferred due to friction
The rate of energy transfer
Work is defined as the application of force over a displacement in the direction of that force (Work = Force Ă - Distance). This distinguishes work from other concepts such as energy or power.
Which of the following best describes gravity?
A measure of speed
A type of energy
A push that objects experience
A force of attraction between two masses
Gravity is the force of attraction that acts between any two masses, drawing them toward each other. It is a fundamental force in physics and is distinct from other concepts like energy or speed.
Calculate the kinetic energy of a 1500 kg car moving at 20 m/s.
150,000 Joules
20,000 Joules
300,000 Joules
600,000 Joules
Using the kinetic energy formula KE = ½ m v², substitute m = 1500 kg and v = 20 m/s to obtain ½ à - 1500 à - (20²) = 300,000 Joules. The other options arise from common calculation errors.
During collisions without external forces, which quantity remains conserved?
Speed
Force
Kinetic Energy
Momentum
In an isolated system where no external forces act, the principle of conservation of momentum applies, meaning total momentum before and after collision remains the same. Kinetic energy, however, might not be conserved especially in inelastic collisions.
What does the slope of a displacement-time graph represent?
Time
Acceleration
Velocity
Displacement
The slope of a displacement-time graph indicates the rate at which displacement changes over time, which is the definition of velocity. A constant slope corresponds to constant velocity, while changes in the slope indicate acceleration.
For an object in free fall near Earth, what acceleration does it experience (ignoring air resistance)?
Approximately 9.8 m/s² downward
Approximately 19.6 m/s² downward
Approximately 0 m/s²
Approximately 9.8 m/s² upward
An object in free fall near Earth's surface accelerates downward at approximately 9.8 m/s² due to gravity. The other options either reverse the direction or incorrectly double the acceleration.
In the gravitational force formula F = G*(m1*m2)/r², what does r represent?
The force experienced by each mass
The sum of the masses
The gravitational constant
The distance between the centers of the two masses
In the equation for gravitational force, r represents the distance between the centers of the two masses. This distance is squared in the denominator, indicating that the force decreases rapidly as the separation increases.
What is the work done when a 10 N force moves an object 5 meters in the direction of the force?
5 Joules
50 Joules
15 Joules
10 Joules
Work is calculated as the product of force and displacement (Work = Force Ă - Distance). Therefore, 10 N multiplied by 5 m gives 50 Joules of work done.
Which of the following best describes potential energy?
Energy in motion
Energy lost as heat
Energy that is not measurable
Energy stored due to an object's position or configuration
Potential energy is the energy stored within an object due to its position, configuration, or state. It is distinct from kinetic energy, which is the energy of motion.
How does increasing an object's mass affect its gravitational force with the Earth?
It has no predictable effect
The gravitational force increases
The gravitational force decreases
The gravitational force remains the same
Gravitational force is directly proportional to the mass of the object, meaning that as mass increases, the gravitational force increases as well. This is a key component in Newton's law of universal gravitation.
Which measurement is used to quantify an object's inertia?
Velocity
Acceleration
Mass
Weight
Inertia is a measure of an object's resistance to changes in its motion, and it is quantified by mass. The larger the mass, the greater the inertia, regardless of the object's weight or speed.
What function does air resistance serve for a falling object?
It has no effect on motion
It reverses the direction of fall
It increases the gravitational force
It opposes the motion, reducing acceleration
Air resistance acts as a force that opposes the motion of a falling object, thereby reducing its net acceleration compared to free fall. This is why objects eventually reach terminal velocity when falling through the atmosphere.
When two objects collide and stick together, what type of collision is this?
Explosive collision
Rebounding collision
Elastic collision
Perfectly inelastic collision
A collision where the two objects stick together is known as a perfectly inelastic collision. In such collisions, momentum is conserved even though some kinetic energy is lost as other forms of energy.
Which statement best applies the principle of conservation of energy?
Energy is only conserved in mechanical systems
Energy cannot be created or destroyed, only transformed
Energy is constantly increasing in a closed system
Energy can vanish without any trace
The principle of conservation of energy states that the total energy in an isolated system remains constant; it can neither be created nor destroyed, only transformed. This fundamental concept applies to all types of energy conversions.
What type of energy conversion occurs in a hydroelectric power plant?
Chemical energy to thermal energy
Electrical energy to nuclear energy
Kinetic energy to potential energy only
Potential energy to kinetic energy to electrical energy
In a hydroelectric power plant, water stored at height (potential energy) flows downward (kinetic energy) and drives turbines to produce electrical energy. This multi-stage energy conversion is a classic example of energy transformation in renewable energy systems.
Which of the following is true about frictional force?
Friction always opposes the motion between surfaces in contact
Friction is independent of the surface properties
Friction has no effect when surfaces are rough
Friction always aids the motion between surfaces in contact
Friction is the resistive force that acts opposite to the direction of motion when two surfaces are in contact. Its magnitude depends on the surfaces involved and the normal force between them, hence it always works against the motion.
A ball thrown upward reaches the peak of its trajectory. What is true at that moment?
The vertical velocity is zero, but acceleration due to gravity remains
Acceleration due to gravity is zero at the peak
The vertical velocity is at its maximum
Both the vertical velocity and acceleration are zero
At the peak of its upward trajectory, the ball momentarily has zero vertical velocity; however, gravity continues to accelerate it downward at approximately 9.8 m/s². This constant acceleration is the reason the ball eventually begins its descent.
