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 ÷ 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?
If a Car is traveling at 40m/s for 10sec what is the distance it will travel?
What is 400 m?
D= S x T
D= 40 x 10
D= 400m
This must act on an object in order for the direction or speed of an object to change
What is an unbalanced force?
An athlete runs around a track that is 100 meters long three times, then stops. What is his total distance traveled?
What is 300 m?
The acceleration due to gravity
What is -9.8 m/s2
The attractive force that acts on all objects everywhere all the time
What is gravity?
The two forces acting on a ball thrown into the air?
What is air resistance and gravity?
The definition of acceleration
What is the rate of change in velocity?
The mass of an object that is traveling at 20m/s2 and has a force of 10,000N
What is 500kg?
M= 10,000 / 20
M= 500kg
According to Newton’s second law of motion, force is equal to mass times_________.
What is acceleration?
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 ?
A plane moves with a velocity of 63.5 m/s at 32 degrees South of East. Calculate the difference between the plane's horizontal and vertical velocity components in km/h.
72.8 km/h
The distance a car travelled if it drove at 40 m/s for 30 minutes
What is 7200 m?
D = v*t = 40 m/s * 1800 s
The mass of an object that is traveling at acceleration of 20m/s2 and a force of 10,000N
What is 500kg?
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
What are Force and Mass?
The force that would be less if you were on the moon
What is weight?
A bear, searching for food wanders 35 meters east then 20 meters north. Frustrated, he wanders another 12 meters west then 6 meters south. Calculate the bear's displacement.
26.93 m, NORTH of EAST
