Forces and Motion

Front

What is a force?

Back

A force is a push or pull that can change the motion of an object.

Front

What happens when forces are balanced?

Back

When forces are balanced, the total force is zero, and there is no change in motion.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes a change in the motion of an object.

Front

What is kinetic energy?

Back

Kinetic energy is the energy that an object has due to its motion.

Front

What is potential energy?

Back

Potential energy is stored energy that has the potential to do work.

Front

How can a force change an object's motion?

Back

A force can change an object's speed, direction, or both.

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces in contact.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other, such as the Earth pulling objects toward its center.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the relationship between mass and force?

Back

The greater the mass of an object, the more force is needed to change its motion.
