Physics of Motion
The unit for force
Newton
A measure of the amount of matter in the object? M=W/G
mass
On Saturn your weight would
increase
Formula to calculate Speed??
speed = distance รท time
Forces occurring between objects and the surfaces they are on or in contact
friction
The energy of motion
Kinetic energy
Maximum speed reached by a falling body
terminal 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 or Law of Inertia
push or pull
force
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.
what is the rate of change in velocity
acceleration
unit of acceleration
m/s2
The unit for work and energy
Joule
The equation for force
What is F = MA
The force of gravity on the object and may be defined as the mass times the acceleration of gravity
weight
The unit of mass
a disturbance in a medium that carries energy without a net movement of particles
wave
If a Car is traveling at 40m/s for 30 minutes what is the distance it will travel in kilometers?
What is 72km
D= 40 m/s x 1800 s
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
What is 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 or Law of Acceleration
the value of acceleration due to gravity
9.8 m/s2
sound wave is an example of what type of wave?
Longitudinal wave?
