Net Forces and Motion Concepts

Front

What is the net force when two equal forces act in the same direction?

Back

Add the forces.

Front

If two forces of 5 N and 3 N act in the same direction, what is the net force?

Back

8 N.

Front

What is the definition of net force?

Back

The overall force acting on an object after all the forces are combined.

Front

What are Newton's 3 Laws of Motion?

Back

1. Law of Inertia, 2. Law of Force and Acceleration, 3. Law of Action-Reaction.

Front

Does friction help objects to move easier?

Back

False.

Front

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

Back

Subtract the smaller force from the larger force.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m*a).

Front

What is the unit of force?

Back

Newton (N).

Front

If a 10 kg object is accelerating at 2 m/s², what is the net force acting on it?

Back

20 N.
