Physics of Motion
This is the unit for force
Newton
This term describes the amount of matter in an object
M=W/G
Mass
“Energy cannot be created or destroyed. It can only be transferred” is the definition for __________.
The Law of Conservation of Energy
This is the formula to calculate Speed
Distance ÷ time
Forces occurring between objects and the surfaces they are on
Friction
This type of energy describes motion
Kinetic energy
Animals are made up of a certain mass. True or False?
False
This is the change (+ or -) to your weight if you were transported to Saturn
Increase
This must act on an object in order for the direction or speed of an object to change
An unbalanced force
"An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same velocity unless acted upon by an unbalanced force" describes which law?
Newton's First Law
The higher up an object is the more _______________ energy it has.
Potential
The attractive force that acts on all objects everywhere all the time
Gravity
Another term for the energy transfer that occurs when an object is moved over a distance
Work
The definition of acceleration
The rate of change in velocity
Newton’s 3rd Law states that for every action there is an ___ and ______ reaction.
Equal and Opposite.
The unit for work and energy
Joules
According to Newton's second law, the equation for force
F = m*a
The force of gravity on the object; may be defined as the mass times the acceleration due to gravity
Weight
The difference between Speed and velocity
Direction / vector
Massive objects are more attractive according to which law?
The distance a car travelled if it drove at 40 m/s for 30 minutes
D = v*t = 40 m/s * 1800 s
D= 72,000 m = 72 km
The mass of an object that is traveling at acceleration of 20m/s^2 and a force of 10,000N
M= F/a = 10,000 / 20
M= 500kg
These are the two variables or things in a physical space that determine what the acceleration of an object will be
Force and Mass
The force that would be less if you were on the moon
Weight
The amount of kinetic energy we would expect a ball to have at the bottom of a hill if it started with a gravitational potential energy (GPE) of 300J
300 J
