Newton's 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 at a constant velocity unless acted upon by a net external 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)

What is Newton's 3rd Law of Motion?

Back

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

What is the difference between mass and weight?

Back

Mass is how much matter is in an object, and weight is the gravitational pull on that mass.

Front

If a net force is applied to an object, what happens to its motion?

Back

The object will accelerate in the direction of the net force.

Front

What happens to the acceleration of an object if the net force acting on it is doubled while its mass remains constant?

Back

The acceleration doubles.

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 when a constant force is applied?

Back

Greater mass results in less acceleration when the same force is applied.

What is the formula for calculating weight?

Back

Weight (W) = mass (m) × gravitational acceleration (g). (W=mg)

What is the role of friction in motion?

Back

Friction opposes the motion of an object and can cause it to slow down or stop.
