2022 Newton's Laws of Motion Review

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What does inertia refer to?

Back

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

Front

How is weight calculated?

Back

Weight is calculated as mass multiplied by the acceleration due to gravity (W = m * g).

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is a vector?

Back

A vector is a quantity that has both magnitude and direction.

Front

What is the formula for calculating weight in pounds from mass in kilograms?

Back

Weight (lbs) = Mass (kg) * 2.20462.

Front

What does it mean for an object to be in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero.

Front

What is the significance of the acceleration due to gravity?

Back

The acceleration due to gravity (approximately 9.81 m/s² on Earth) affects the weight of objects.

Front

What is the relationship between mass and inertia?

Back

Objects with greater mass have greater inertia, meaning they resist changes in motion more than lighter objects.

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 unless acted upon by a net external force.
