Applying Newton's 3 Laws of Motion

Front

What is Newton's 1st 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 2nd 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 3rd Law of Motion?

Back

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

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does mass affect acceleration according to Newton's 2nd Law?

Back

A larger mass requires a greater force to achieve the same acceleration as a smaller mass.

Front

What is an example of Newton's 1st Law in everyday life?

Back

A magician pulling a tablecloth from under dishes without moving them demonstrates inertia.

Front

What does Newton's 3rd Law explain in sports?

Back

When two players tackle each other, they exert equal and opposite forces, causing them to move in opposite directions.

Front

What is the relationship between force, mass, and acceleration?

Back

Force equals mass times acceleration (F = ma). This means that for a given force, increasing mass will decrease acceleration.

Front

What happens to a sled on a flat, icy surface with no friction?

Back

It will continue to slide at a constant velocity due to Newton's 1st Law.

Front

What is an example of an unbalanced force?

Back

A football being kicked is an example of an unbalanced force acting on the ball.
