Force & Net Force

Front

What is force?

Back

A push or pull on an object that can cause it to move, stop, or change direction.

Front

What is net force?

Back

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

Front

What happens when forces are balanced?

Back

The object remains at rest or continues to move at a constant speed in a straight line.

Front

What happens when forces are unbalanced?

Back

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, where the force of gravity is balanced by the normal force from the table.

Front

What is an example of an unbalanced force?

Back

A soccer ball being kicked, where the force of the kick is greater than the forces acting against it.

Front

What is the direction of net force if an object moves to the left?

Back

The net force is also directed to the left.

Front

How can you determine if forces are balanced or unbalanced?

Back

If the net force is zero, the forces are balanced; if the net force is not zero, the forces are unbalanced.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the unit of force?

Back

Newton (N).
