Back

The wall pushes back against the swimmer with the same amount of force.

Front

What is net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

What is the net force if two forces of 30 N act in opposite directions?

Back

0 N (balanced forces).

Front

What is gravitational potential energy (GPE)?

Back

The energy an object possesses due to its position in a gravitational field.

Front

At what point does a ball have the most GPE when thrown into the air?

Back

At its highest point.

Front

What is the formula for calculating net force?

Back

Net Force = Total Forces acting in one direction - Total Forces acting in the opposite direction.

Front

What is an example of an unbalanced force?

Back

A soccer ball being kicked in one direction.

Front

What is the effect of balanced forces on an object?

Back

The object remains at rest or continues to move at a constant speed.

Front

What is the force of gravity on a 10 kg object on Earth?

Back
