Newton's Laws of Motion Bellringer

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 does Newton's 2nd Law of Motion state?

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 a Newton?

Back

A unit of force in the International System of Units (SI), defined as the force required to accelerate a one-kilogram mass by one meter per second squared.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = ma).

Front

What is a force?

Back

Any push or pull on an object.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the relationship between mass and acceleration according to Newton's 2nd Law?

Back

As mass increases, acceleration decreases if the force remains constant.

Front

What is the significance of unbalanced forces?

Back

Unbalanced forces cause an object to change its state of motion (accelerate).

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

How does mass affect the force required to accelerate an object?

Back

Greater mass requires a greater force to achieve the same acceleration.
