Back

Net force

Front

An object is in equilibrium if it is moving in a straight line at what type of speed?

Back

Constant speed (includes remaining at rest)

Front

What type of friction acts when something is moving along a surface and opposes the direction of motion?

Back

Front

What is the term for the total force acting on an object when all individual forces are combined?

Back

Net force

Front

What is the term for the friction that prevents an object from starting to move?

Back

Static friction

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on mass.

Front

What happens to the net force when all forces acting on an object are balanced?

Back

The net force is zero.

Front

What is the effect of increasing the mass of an object on its weight?

Back

Weight increases as mass increases.
