Gravity Physics
Answer true or false to the statement:
Mass and Weight are the same.
False
Earth's velocity (in m/s2)
What is 9.8 m/s2?
A relationship between two units
What is rate?
The rate at which velocity changes in an object; for example, when something speeds up or slows down
What is acceleration?
This term refers to the amount of matter in an object
What is mass?
The equation that gives the time it takes an object to fall a certain distance
What is "t=√(2d/a)"
The speed of an object in a certain direction
What is velocity?
State the unit used for acceleration
(hint: think of it as a rate)
What is m/s2?
This term refers to the amount of force on an object due to gravity
What is weight?
An object drops from 200m above Earth's surface. Approximetely when will it hit the ground? (Do not include air resistance factors)
What is 6.39 seconds?
(The rate of) how fast an object travels at
What is speed?
Find the acceleration of a bus accelerating to 14 m/s in 4 seconds
What is 3.5 m/s2?
What are Newtons?
State the equation that finds the speed at which an object travels after a certain time
What is "vt = vi + a*t"?
The magnitude of an object, but not its direction
What is scalar?
DAILY DOUBLE:
Acceleration is this type of quantity
What is vector?
Sir Issac once said: "The force of gravity acts between all objects in the universe - any two objects in the universe attract each other." What is this law?
What is "Newton's Universal Law of Gravitation"?
This equation finds how far an object has traveled after a certain time
What is "dt = vi*t + 0.5a*t2"?
The magnitude and direction of an object
What is vector?
This equation calculates the acceleration of an object
What is "a = v-v0/t"
