Newton’s First Law
of Motion
Newton’s Second Law
of Motion
Objects at rest remain at rest.
Objects in motion remain in motion
in a straight line unless acted upon.
Force equals mass times acceleration
Newton’s Third Law
of Motion
For every action there is an
equal and opposite reaction.
The amount of matter contained in an object,
such as the amount of air contained in a
balloon or the amount of water in a glass.
Unless altered, this remains the same
whether the object is on Earth, in Earth orbit,
or on the Moon.
It represents the force of gravity
acting on a mass.
This quantity will change depending on the
force of gravity acting on the object.
F = m ×g
Force multiplied by the amount of
time it acts over.
Also, the change in momentum.
A change in either the speed or
direction of motion.
For example, when you step on the
accelerator pedal of a car, you cause
in increase in this.
A Push or a pull exerted on an object.
Examples include muscle power,
movement of air, and electromagnetism.
When an object is at rest, this is
balanced. When an object is in motion,
this is unbalanced.
All matter, because of its mass,
resists changes in motion.
The more mass, the more resistance.
The quantity of motion affecting an
Mass times velocity.
Other possible ideas:
Gravity - The force of attraction between masses. Gravity is the force that makes objects fall to the ground.
