Net Forces

Front

What is a 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 motion.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses. It is the force that keeps planets in orbit around the sun.

Front

What happens when forces are balanced?

Back

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

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the net force is not zero, causing the object to accelerate in the direction of the larger force.

Front

How do you determine the direction of net force?

Back

The direction of the net force is the same as the direction of the larger force when forces are unbalanced.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

If an object has a net force of 35 N to the right, what does this indicate?

Back

This indicates that the total force acting on the object is 35 N in the right direction, causing it to accelerate to the right.

Front

What is air resistance?

Back

Air resistance is a type of frictional force that opposes the motion of an object through the air.

Front

What is the effect of increasing mass on gravitational force?

Back

Increasing the mass of an object increases the gravitational force acting on it, as gravitational force is directly proportional to mass.

Front

What is the effect of distance on gravitational force?

Back

Gravitational force decreases as the distance between two objects increases, following the inverse square law.
