Energy
What is the difference between Kinetic Energy and Potential Energy
Kinetic Energy is energy used during movement; Potential Energy is energy that is not moving but has the potential to do so.
What is the unit of measure used when calculating Work done?
Joule
Name the unit of measure of power
1 watt or 1 Joule*sec
What is Momentum
the quantity of motion of a moving body, measured as a product of its mass and velocity. The mass of a moving body times the velocity it's moving.
Velocity and Speed are different because velocity also includes speed and __________?
Direction
Can Energy be created and/or destroyed?
No. The law of conservation of energy says energy can neither be created nor destroyed.
What is the equation for Work?
W=Fd
Define Power as it pertains to Physics.
amount of energy transferred or converted per unit time.
What is the equation for Momentum?
p=mv
A car travels a distance of 100 meters in 20 seconds. 1. Solve for how much distance is traveled in how much time.
2. Is it speed or velocity?
What is the equation for Potential Energy
PE=mgh
What is the unit of Work?
N*m
What is the equation for Power?
P=w/t
What is the unit of measure for momentum?
N*s or a Newton per second
When graphing or describing direction which variable is used to represent vertical motion and which variable is used to represent horizontal motion?
x represents horizontal motion
y represents vertical motion
What is the equation for Kinetic Energy?
KE=1/2 mv^2
Why would a moving truck knock a person down but a small child running towards a person NOT knock them down? What variable determines this?
The mass of the object
Which general type of measurement is Velocity considered to be? Ie. Scalar, Vector, Magnitude, etc
