Forces Review

Front

What is NET FORCE?

Back

The overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

What is a balanced force?

Back

When two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

When two forces acting on an object are not equal, causing the object to accelerate in the direction of the greater force.

Front

Does every object with mass have gravity?

Back

Yes, every object with mass exerts a gravitational force.

Front

What is static friction?

Back

The force that keeps an object at rest and prevents it from moving when a force is applied.

Front

What is sliding friction?

Back

The force that opposes the motion of an object sliding over a surface.

Front

What is rolling friction?

Back

The force that opposes the motion of a rolling object, typically less than sliding friction.

Front

Which is stronger: static friction or sliding friction?

Back

Static friction is generally stronger than sliding friction.

Front

What force slows down a moving ball?

Back

Rolling friction slows down a moving ball.

Front

What is the effect of net force on an object?

Back

Net force determines whether an object will start moving, stop moving, or change direction.
