Forces Flashcard (Honors)

Front

What is Newton's Third Law of Motion?

Back

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

Front

Define mass in physics.

Back

Mass is the amount of matter in an object, typically measured in kilograms.

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as mass times the acceleration due to gravity (W = mg).

Front

How do mass and weight differ?

Back

Mass is a measure of the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What happens to the forces acting on an object when it is in free fall?

Back

The only force acting on the object is gravity, resulting in a net force equal to its weight.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's Second Law, force equals mass times acceleration (F = ma).

Front

What is an interaction force pair?

Back

An interaction force pair consists of two forces that are equal in magnitude and opposite in direction, acting on two different objects.

Front

What does it mean for forces to be balanced?

Back

Balanced forces occur when the net force acting on an object is zero, resulting in no change in motion.

Front

What is the significance of the upward force in an elevator moving downward and slowing down?

Back

The upward force is greater than the downward force, causing the elevator to decelerate.

Front

What is the effect of gravity on an object's weight?

Back

Gravity pulls objects toward the center of the Earth, determining their weight based on their mass.
