Front

According to Newton's First Law, what can we conclude about a ball rolling at a constant velocity on a frictionless surface?

Back

The forces acting on the ball are balanced.

Front

If two forces of 10N and 5N act in opposite directions, what is the net force?

Back

The net force is 5N in the direction of the 10N force.

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy increases with mass; if mass increases, kinetic energy increases if velocity remains constant.
