Newton's Laws and Momentum

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 the formula for calculating force?

Back

Force = Mass x Acceleration (F = ma)

Front

What is the acceleration due to gravity near Earth's surface?

Back

9.8 m/s².

Front

What happens to an object in motion when no net force acts on it?

Back

It continues to move at a constant velocity.

Front

What is momentum?

Back

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

Front

How does mass affect momentum?

Back

Greater mass results in greater momentum if velocity is constant.

Front

What is the relationship between force and acceleration?

Back

Force is directly proportional to acceleration; as force increases, acceleration increases.

Front

What is inertia?

Back

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