8th Grade Physical Science GMAS Review

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It is highest when the object is at its highest point.

Front

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

Back

According to Newton's second law, force equals mass times acceleration (F = ma). This means that the greater the mass of an object, the more force is needed to accelerate it.

Front

What is ductility?

Back

Ductility is the ability of a material to be stretched into a wire without breaking.

Front

What is an electron?

Back

An electron is a subatomic particle that has a negative charge and orbits the nucleus of an atom.

Front

What does it mean for forces to be balanced?

Back

Balanced forces occur when two forces acting on an object are equal in size but opposite in direction, resulting in no net force and no change in motion.

Front

What is the formula for calculating net force?

Back

Net force is calculated by adding all the forces acting on an object, taking into account their directions.

Front

What is kinetic energy?

Back

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

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is mass?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can occur due to a change in speed or direction.
