Physics of Motion
The unit for force
Newton
A measure of the amount of matter in the object? M=W/G
Mass
What is the formula for momentum?
p = mv
Formula to calculate Speed??
Distance รท time
Forces occurring between objects and the surfaces they are on
Friction
The energy of motion
Kinetic energy
Maximum speed reached by a falling body
Velocity
He is often referred to as one of the "Founding Fathers" of modern physics.
Sir Isaac Newton
"Every object retains its state of rest or state of uniform straight line motion unless acted on by an unbalanced force"
Newton's First Law
the term for a solid that converts directly to a gas?
Sublimation
Work done over a period of time
Power
The attractive force that acts on all objects everywhere
Gravity
Another term for the energy transfer that occurs when an object is moved over a distance
Work
Define Acceleration.
Rate of change in velocity.
the normal range for human hearing
20-20,000 Hz
The unit for work and energy
Joule
The equation for force
F = ma
The force of gravity on the object and may be defined as the mass times the acceleration of gravity
Weight
The difference between Speed & Velocity?
Direction / vector
Final velocity minus Initial velocity divided by the acceleration
Time
If a Car is traveling at 40m/s for 30 minutes what is the distance it will travel in kilometers?
72km
D= 40 m/s x 1800 sec
D= 72000 m = 72 km
The mass (with correct unit) of an object that is traveling at 20m/s^2 and has a force of 10,000N
500kg
M= 10,000 / 20
M= 500kg
This scientific "principle" states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. OR F=M*A
Newton's 2nd Law
On the moon your _____ would be less
weight
It is the result of the square root of the square of the X component plus the square of the Y component
resultant Vector or resultant Force
