Newton's Laws of Motion CCA #3 Hyperdoc

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.

Front

What is the formula for calculating force?

Back

F = ma (Force equals mass times acceleration).

Front

What does inertia refer to in physics?

Back

Inertia is 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

What is Newton's Third Law of Motion?

Back

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

Front

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

Back

200 Newtons.

Front

What happens to a passenger in a car when it suddenly stops?

Back

The passenger continues moving forward due to inertia until an unbalanced force (the seatbelt) acts on them.

Front

What is an example of an unbalanced force?

Back

A car accelerating when the driver presses the gas pedal.

Front

What is the relationship between mass and acceleration in Newton's Second Law?

Back

As mass increases, acceleration decreases if the same force is applied.

Front

What is an example of Newton's Third Law in action?

Back

When you jump off a small boat, the boat moves backward as you move forward.
