Energy and Collisions Test

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, causing it to slow down or stop.

Front

What happens to a moving object when it collides with another object?

Back

The motion of the moving object can change; it may slow down, stop, or change direction.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity, which can involve speeding up, slowing down, or changing direction.

Front

What factors affect the acceleration of an object?

Back

Acceleration depends on the force acting on the object and the mass of the object.

Front

What is the role of gravity in motion?

Back

Gravity pulls objects towards the Earth, affecting their motion, especially when they are on ramps or falling.

Front

What happens to the speed of a ball when it is kicked?

Back

The speed of the ball increases, causing it to move faster.

Front

What is a collision?

Back

A collision is an event where two or more objects hit each other, affecting their motion.

Front

How does height affect the distance a toy car travels down a ramp?

Back

A higher ramp gives the car more potential energy, which can result in it traveling a longer distance.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.
