Newton's Laws (Unit 4)

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 at a constant velocity unless acted upon by a net external force.

Front

What is the formula for calculating momentum?

Back

Momentum (p) = mass (m) × velocity (v).

Front

What is the relationship between force and acceleration according to Newton's Second Law?

Back

Force is directly proportional to acceleration (F = ma).

Front

What does Newton's Third Law state?

Back

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

Front

How does mass affect acceleration when a constant force is applied?

Back

As mass increases, acceleration decreases (inverse relationship).

Front

What happens to the momentum of an object if its velocity doubles?

Back

The momentum of the object also doubles.

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N).

Front

If a 50 kg ball rolls at 5 m/s, what is its momentum?

Back

250 kg*m/s.

Front

What is the effect of balanced forces on a moving object?

Back

It will continue to move at a constant velocity.

Front

What is the relationship between mass and inertia?

Back

Inertia is directly proportional to mass; more mass means more inertia.
