MOD QSE 2 Test Review

Front

What does it mean for an object to be balanced?

Back

An object is balanced when its Net Force is 0 N, meaning all forces acting on it are equal and opposite.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or height. At the top of a hill, a roller coaster has maximum potential energy.

Front

What are energy transformations?

Back

Energy transformations are changes from one form of energy to another. For example, in a battery-operated radio, energy transforms from chemical to electrical to sound.

Front

What is Newton's Third Law of Motion?

Back

Newton's Third Law states that for every action, there is an equal and opposite reaction.

Front

What is an action force?

Back

An action force is the initial force applied to an object, such as pulling back a bowstring before releasing it.

Front

What is net force?

Back

Net force is the total force acting on an object after all the individual forces are combined.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, which depends on its mass and speed.

Front

What is the formula for calculating potential energy?

Back

Potential energy (PE) = mass (m) × gravity (g) × height (h).

Front

What is the relationship between potential energy and height?

Back

Potential energy increases as the height of an object increases.

Front

What is inertia?

Back

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