Newtons laws
What is newtons first law of energy?
an object stays at rest or in motion unless a force acts on it
This type of energy increases as an object’s speed increases.
Kinetic Energy
What is the joule (J)?
This SI unit measures energy, whether it’s food energy or mechanical energy.
What is speed?
the distance an object travels per unit of time.
what is a balanced force?
Forces acting on an object are equal in size and opposite in direction.
What is Newton’s Second Law?
This law explains why pushing a heavier object requires more force to get the same acceleration.
This form of energy travels in waves and includes visible light, microwaves, and X‑rays.
electromagnetic energy
What is the newton (N)?
This SI unit is used to measure force.
What is mass?
the amount of matter in an object.
what is an unbalanced force?
Forces acting on an object are not equal.
What is Newton’s Third Law?
This law states that for every action, there is an equal and opposite reaction.
This type of energy is stored in the bonds of molecules and released during reactions like burning fuel.
chemical energy
What is the watt (W)?
This unit measures power, or how fast energy is used or transferred.
What is inertia?
the tendency of an object to resist changes in its motion
which law is this 1st, 2nd, or 3rd? A boy going down a slide and as he reaches the bottom, friction causes him to slow down and stop.
First law
How are inertia and mass related?
Inertia and mass are tightly connected — mass is essentially the measure of an object’s inertia.
This form of energy is released when the nucleus of an atom is split or combined.
nuclear energy
What is meters per second (m/s)?
This unit measures the speed of an object, often written as distance per time.
What is force?
a push or a pull that can change an object’s motion.
which law is this 1st, 2nd, or 3rd? Two bumper cars collide into each other and their cars jolt backwards.
Third law
How does mass affect acceleration?
More mass → less acceleration when the same force is applied.
This type of energy is produced when particles move faster as temperature increases.
thermal energy
What is the kilogram (kg)?
This SI unit measures the amount of matter in an object.
What is velocity?
the speed of an object in a specific direction.
which law is this 1st, 2nd, or 3rd? Force = mass x acceleration.
Second Law
