Which Law is it? Review

Front

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

Back

This statement describes Newton's 3rd Law of Motion, which states that forces always occur in pairs. When one object exerts a force on another, the second object exerts a force of equal magnitude and opposite direction on the first object.

Front

A car accelerates faster than a truck.

Back

This scenario illustrates Newton's 2nd Law of Motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma). A lighter object (car) will accelerate faster than a heavier object (truck) when the same force is applied.

Front

The Law of Inertia.

Back

This is another name for Newton's 1st Law of Motion, which states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by an unbalanced force.

Front

The air is let out of a balloon and it flies around the room.

Back

This demonstrates Newton's 3rd Law of Motion, where the air rushing out of the balloon creates a force in the opposite direction, propelling the balloon forward.

Front

An object at rest will remain at rest and an object in motion will remain in motion until acted upon by an unbalanced force.

Back

This is a statement of Newton's 1st Law of Motion, emphasizing the concept of inertia.

Front

What is Newton's 1st Law of Motion?

Back

Newton's 1st Law of Motion states that an object will not change its state of motion unless a net external force acts on it.

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law of Motion states that the acceleration of an object is dependent on the mass of the object and the amount of force applied (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

Newton's 3rd Law of Motion states that for every action, there is an equal and opposite reaction.

Example of Newton's 1st Law in everyday life.

Back

A book resting on a table will remain at rest until someone picks it up (an unbalanced force acts on it).

Example of Newton's 2nd Law in everyday life.

Back

Pushing a shopping cart: a lighter cart accelerates faster than a heavier one when the same force is applied.
