Newton's Laws of Motion

Front

What is Newton's 1st Law of Motion?

Back

The Law of Inertia: An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is Newton's 2nd Law of Motion?

Back

The Law of Force and Acceleration: The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

The Law of Action and Reaction: For every action, there is an equal and opposite reaction.

Front

Define inertia.

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

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

Back

Due to inertia, the passenger will continue moving forward, pressing against the seatbelt.

Front

If two people pull on a rope with equal force, what will happen?

Back

They will not move at all; the forces are balanced.

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

Give an example of Newton's 1st Law in everyday life.

Back

A book resting on a table will remain at rest until someone pushes it.

Front

What is the relationship between mass and acceleration in Newton's 2nd Law?

Back

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

Front

How does Newton's 3rd Law apply to walking?

Back

When you push down on the ground, the ground pushes you up with an equal and opposite force.
