Net Forces Review

Front

What is a force?

Back

A force is the PUSH or PULL on an object.

Front

What is the net force?

Back

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

Front

What does it mean if forces are balanced?

Back

If forces are balanced, the net force is 0 N, and the object does not accelerate.

Front

What is an unbalanced force?

Back

An unbalanced force results in a net force that causes an object to accelerate.

Front

How do you calculate net force?

Back

Net force is calculated by adding all the forces acting on an object, taking direction into account.

Front

What is the direction of the net force if 40 N right and 40 N left are acting on an object?

Back

The net force is 0 N, meaning the forces are balanced.

Front

If an object has a net force of 3 N to the right, what can we say about its motion?

Back

The object will accelerate to the right.

Front

What happens to an object at rest if no net force acts on it?

Back

The object remains at rest.

Front

What happens to an object in motion if no net force acts on it?

Back

The object continues to move at a constant velocity.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.
