Newton's Laws, Motion, & Forces

Front

What is Newton's third law of motion?

Back

For every action force, there is an equal and opposite reaction force.

Front

What does Newton's first law of motion state?

Back

The motion of an object does not change if the net force on the object is zero.

Front

What principle is illustrated when a magician pulls a tablecloth out from under the dishes without disturbing them?

Back

Newton's first law of motion.

Front

How do you calculate force using mass and acceleration?

Back

Force (F) = Mass (m) × Acceleration (a).

Front

What are balanced forces?

Back

Combined forces that form a net force of zero.

Front

What is inertia?

Back

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

Front

What is Newton's second law of motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

If a 20 kg bike accelerates at 10 m/s², what is the force?

Back

200 Newtons.

Front

What is the formula for calculating net force?

Back

Net Force = Total Forces acting on an object.

Front

What happens to an object in motion if no net force acts on it?

Back

It continues to move at a constant velocity.
