Physics of Motion
This is the unit for force
What is a Newton?
This term describes the amount of matter in an object
M=W/G
What is mass?
The value that results if you multiply mass and velocity; often used to determine fault in car crashes
What is momentum?
This is the formula to calculate Speed
What is distance รท time?
Forces occurring between objects and the surfaces they are on
What is friction?
This type of energy describes motion
What is Kinetic energy?
This is the term for the Maximum speed reached by a falling object
What is terminal velocity?
This is the change to your weight if you were transported to Saturn
What is increase?
This must act on an object in order for the direction or speed of an object to change
What is an unbalanced force?
Force divided by area
Work done over a period of time
What is Power?
The attractive force that acts on all objects everywhere all the time
What is gravity?
Another term for the energy transfer that occurs when an object is moved over a distance
What is work?
The definition of acceleration
What is the rate of change in velocity?
Divide mass by volume, kg/m3
The unit for work and energy
What is Joule?
The equation for total (net) force
What is F = m*a?
The force of gravity on the object; may be defined as the mass times the acceleration due to gravity
What is weight?
The difference between Speed and velocity
What is a direction / vector ?
To calculate power?
Energy transferred % time
The distance a car travelled if it drove at 40 m/s for 30 minutes
What is 72 km?
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
What is 500kg?
M= F/a = 10,000 / 20
M= 500kg
The formula of kinetic energy
1/2 mv2
The force that would be less if you were on the moon
What is 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
What is 300 J?
