Front

How do you calculate net force when two forces act in opposite directions?

Back

Subtract the smaller force from the larger force.

Front

What is the definition of net force?

Back

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

Front

What is the unit of force?

Back

Newton (N).

Front

What does it mean if an object is moving at a constant speed?

Back

The object covers equal distances in equal intervals of time.

Front

How do you determine the direction of net force?

Back

The direction of the net force is the same as the direction of the larger force.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.
