Flashcard on Newtons Law 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 unless acted upon by an external force.

Front

What is an example of the Law of Inertia?

Back

A cycle will continue to move with the same velocity even after you stop pedaling.

Front

What does the First Law explain about a picture hanging on the wall?

Back

It explains that the picture does not move because no external force is acting on it.

Front

What is the formula to calculate weight?

Back

Weight = Mass x Gravity (W = m x g).

Front

If the weight of a body is 100N, what is its mass?

Back

10.20 kg.

Front

What does the Law of Interaction state?

Back

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

Front

What happens to the mass of an object when it is moved from Earth to the Moon?

Back

The mass stays the same.

Front

What is the definition of mass?

Back

Mass is the amount of matter in an object.

Front

What is the difference between mass and weight?

Back

Mass is constant and does not change with location, while weight is the force of gravity on an object and can change with location.

Front

What is an example of an action-reaction pair?

Back

When you push against a wall, the wall pushes back with equal force.
