Flashcard: Fundamentals of Physics and Energy — 10 carte

Newton's 3rd Law — definition?

For every action, there's an equal and opposite reaction.

Position vs. Time — slope?

Represents the velocity of the object.

Independent Variable — role?

The factor changed by the experimenter.

Physical vs. Chemical — change?

Physical changes affect form; chemical changes create new substances.

Energy conservation — principle?

Energy cannot be created or destroyed, only transformed.

Force pair — example?

Two forces equal in magnitude, opposite in direction, acting on different objects.

Constant slope — indicates?

Constant velocity in position-time graph.

Constants — purpose?

Variables kept the same to ensure fair testing.

Change of state graph — feature?

Temperature plateau during phase transitions.

Kinetic energy — depends on?

Object’s speed.
