Force & Net Force

Front

What is force?

Back

A force is a push or pull acting on an object.

Front

What is net force?

Back

Net force is the total force acting on an object after all the forces are combined.

Front

What happens when forces are balanced?

Back

When forces are balanced, the object remains at rest or continues to move at a constant speed.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the object will accelerate in the direction of the net force.

Front

What is an example of a balanced force?

Back

A book resting on a table is an example of balanced forces; the force of gravity is balanced by the normal force from the table.

Front

What is an example of an unbalanced force?

Back

Pushing a stationary car to get it moving is an example of an unbalanced force.

Front

How do you calculate net force?

Back

To calculate net force, add all the forces acting in one direction and subtract the forces acting in the opposite direction.

Front

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

Back

The net force is 15N.

Front

If a force of 10N acts to the right and a force of 5N acts to the left, what is the net force?

Back

The net force is 5N to the right.

Front

What is the unit of force?

Back

The unit of force is Newton (N).
