What is the unit used to measure force?

Back

The unit used to measure force is the Newton (N).

Front

What does a net force of 3 N indicate about the forces acting on an object?

Back

A net force of 3 N indicates that there is an unbalanced force acting on the object, resulting in acceleration.

What happens to an object when the net force acting on it is not zero?

Back

When the net force acting on an object is not zero, the object will accelerate in the direction of the net force.

What is an example of balanced forces?

Back

An example of balanced forces is when two people push a stationary car with equal force in opposite directions.

Front

How do you calculate net force when multiple forces are acting on an object?

Back

To calculate net force, sum all the forces acting on the object, taking into account their directions.
