The Way You Move Flashcards
Newton’s first law
Law of INERTIA
an object at rest tends to stay at rest until a Ted upon by an outside force.
The greater the force the …. INERTIA and requires …. force to move object at rest.

Newton’s second law
Force = mass x acceleration
When an unbalanced force is applied to an object it causes it to accelerate.
The greater the force that is applied the increase of the acceleration
The lesser the force that is applied the decrease of the acceleration
If the same force is applied to an object with a large mass it will have a decrease in acceleration
If the same force is applied to an object with a small mass it will have a increase in acceleration
Newton’s third law
For every action there is an equal and opposite reaction
Every time there is an upward force that is equal size and acts in the opposite direction
Forces must always act in pairs
Force
A physical quantity you deal with everyday. It is a push or pull exerted by one object on another. The pull or push may come from direct contact or, in the case of gravity, electricity and magnetism from a distance
Force =
Mass x acceleration
Mass =
Force divided by acceleration
Acceleration =
Force divided by mass
Measurements
Acceleration = m/s/s Force = Newton’s Mass = kilograms
Speed =
Distance x time
Distance =
Speed divided by time
Time =
Speed divided by time
Acceleration =
V(final value) - U (initial value) divided by T (time)
Kinetic energy
Energy that all moving objects possess (determined by mass and speed of an object)
K = 1/2 x m x v squared
Potential energy
Stored energy that has not yet been released
P = m x g x h
G = gravity 9.8m/s/s
