Energy and Collisions Test

Front

What is energy?

Back

Energy is the ability to do work or cause change. It can exist in various forms, such as kinetic energy (energy of motion) and potential energy (stored energy).

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion. The faster an object moves, the more kinetic energy it has.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a toy car at the top of a ramp has potential energy.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It occurs when two surfaces rub against each other.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity. It can be an increase or decrease in speed.

Front

What factors affect acceleration?

Back

Acceleration depends on the force acting on an object and the mass of the object. More force leads to more acceleration, while more mass leads to less acceleration.

Front

What happens when two objects collide?

Back

When two objects collide, they exert forces on each other, which can change their motion. One object may speed up, slow down, or change direction.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other. It keeps us on the ground and causes objects to fall.

Front

How does height affect potential energy?

Back

The higher an object is, the more potential energy it has. This is because it has the potential to fall a greater distance.

Front

What is the relationship between force and motion?

Back

A force applied to an object can change its motion. If the force is strong enough, it can make the object speed up, slow down, or change direction.
