Practice Net Force

Front

What is the net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. It determines the object's acceleration and direction.

Front

How do you find the net force when two forces are acting in opposite directions?

Back

You subtract the smaller force from the larger force to find the net force.

Front

What do you do when two forces are acting in the same direction?

Back

You add the magnitudes of the two forces to find the net force.

Front

If a force of 10 N left and a force of 7 N right are acting on an object, what is the net force?

Back

3 N left (10 N left - 7 N right = 3 N left).

Front

If a force of 15 N right and a force of 5 N right are acting on an object, what is the net force?

Back

20 N right (15 N right + 5 N right = 20 N right).

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What happens to the net force if all acting forces are balanced?

Back

If all forces are balanced, the net force is zero, and the object remains at rest or continues to move at a constant velocity.

Front

What is the effect of a net force on an object?

Back

A net force causes an object to accelerate in the direction of the net force according to Newton's second law of motion (F=ma).

Front

If a 50 N force is applied to the right and a 20 N force is applied to the left, what is the net force?

Back

30 N right (50 N right - 20 N left = 30 N right).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.
