Newton's Laws of Motion

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 with the same speed and in the same direction unless acted upon by an unbalanced force.

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. (F = ma)

Front

What is Newton's Third Law of Motion?

Back

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 is force?

Back

A force is a push or pull on an object that can cause it to accelerate.

Front

How do you calculate force?

Back

Force can be calculated using the formula F = ma, where F is force, m is mass, and a is acceleration.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

If a 5 kg object is accelerating at 2 m/s², what is the force acting on it?

Back

10 N (calculated using F = ma: F = 5 kg * 2 m/s²).

Front

What happens to the forces when two objects collide?

Back

They exert equal and opposite forces on each other.

Front

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

Back

As mass increases, for a given force, acceleration decreases.
