Newtons laws and Momentum

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

What is momentum?

Back

Momentum is the product of an object's mass and its velocity (p = mv).

Front

How is mass measured?

Back

Mass is measured in kilograms (kg).

Front

What is the formula to calculate force?

Back

Force (F) is calculated using the formula F = ma, where m is mass and a is acceleration.

Front

If a bug has a mass of 0.05 kg and accelerates at 2 m/s², what is the net force on the bug?

Back

0.1 N.

Front

What happens to the total momentum of a system if no external forces act on it?

Back

The total momentum remains constant.

Front

What is the unit of momentum?

Back

The unit of momentum is kilogram meter per second (kg x m/s).

Front

What is an example of Newton's First Law in everyday life?

Back

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