What is Net Force?

Back

The total balance force acting on an object.

Front

True or False: Net force can change the speed or direction of an object.

Back

True

Front

Calculate the net force acting on an object with a mass of 5 kg and an acceleration of 2 m/s².

Back

10 N

Front

A car is experiencing a net force of 500 N in the forward direction, while another force of 200 N is acting in the opposite direction. What is the net force on the car?

Back

300 N

Front

Calculate the net force acting on an object with a mass of 2 kg and an acceleration of 0 m/s².

Back

0 N

Front

What is the formula to calculate net force?

Back

Net Force = Mass x Acceleration

Front

If an object has a mass of 10 kg and is accelerating at 3 m/s², what is the net force?

Back

30 N

Front

What happens to the net force if two equal forces act in opposite directions?

Back

The net force is zero.

Front

Define acceleration in terms of net force and mass.

Back

Acceleration = Net Force / Mass

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N)
