Net Force Practice

Front

What is net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined.

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 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

If two forces act in the same direction, how do you find the net force?

Back

You add the magnitudes of the two forces together.

Front

If two forces act in opposite directions, how do you find the net force?

Back

You subtract the smaller force from the larger force and the direction of the net force is in the direction of the larger force.

Front

What is an example of unbalanced forces in everyday life?

Back

A marble rolling down a ramp experiences unbalanced forces due to gravity pulling it down.

Front

What is an example of balanced forces in everyday life?

Back

An airplane flying at a constant speed experiences balanced forces when thrust equals drag and lift equals weight.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What does it mean if an object is in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero, resulting in no acceleration.

Front

How does mass affect the net force?

Back

The greater the mass of an object, the greater the net force needed to accelerate it according to Newton's second law (F=ma).
