Force, Motion & Energy - VASOL - 5.3

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion that moving objects possess.

Front

How is motion described?

Back

Motion is described by an object's direction and speed.

Front

What happens when objects collide?

Back

The energy from one object transfers to another, potentially changing the object's speed and/or direction.

Front

What is speed?

Back

Speed describes how fast an object is moving.

Front

What is the principle of inertia?

Back

Unless acted on by a force, objects in motion tend to stay in motion and objects at rest remain at rest.

Front

What is a force?

Back

A force is any push or pull that causes an object to move, stop, or change speed or direction.

Front

How does force affect objects of the same mass?

Back

With objects of the same mass, the greater the force, the greater the change in motion.

Front

How does mass affect the impact of a force?

Back

The more massive an object, the less effect a given force will have on it.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.

Front

What happens when two objects interact?

Back

Each exerts a force on the other, which can transfer energy and cause changes in their motion.
