Net Force Practice

Front

What is net force?

Back

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

Front

What happens when forces are balanced?

Back

When forces are balanced, the net force is zero, meaning the object remains stationary or moves at a constant speed.

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 greater force.

Front

How do you calculate net force when two forces act in the same direction?

Back

You add the magnitudes of the two forces together.

Front

How do you calculate net force when two forces act in opposite directions?

Back

You subtract the smaller force from the larger force and the direction of the larger force will be the direction of the net force.

Front

What unit is force measured in?

Back

Force is measured in Newtons (N).

Front

If a skateboarder is going down a ramp, what type of forces are acting on them?

Back

The forces are unbalanced, as gravity pulls them down the ramp while friction opposes their motion.

Front

What does it mean if an object is stationary?

Back

It means that the net force acting on the object is balanced, resulting in no change in position.

Front

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

Back

Increasing the net force will increase the acceleration of the object according to Newton's second law (F=ma).

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting in the opposite direction to the movement.
