Newton's Laws of Motion

Front

What is Newton's 1st Law of Motion?

Back

An object at rest tends to stay at rest, and an object in motion tends to stay in motion at a constant velocity unless acted upon by an unbalanced force.

Front

What is inertia?

Back

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

Front

What does Newton's 2nd Law of Motion state?

Back

The net force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma).

What happens to a passenger in a car when the driver stops quickly?

Back

The passenger will move forward pressing against the seatbelt due to inertia.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

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

Back

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