The ability to do work or cause change is called?
Energy
Any time you exert a force on an object that causes the object to change its motion in the same direction you exert force is called
Work
What measure is Distance in?
Meters (M)
The rate at which velocity changes over time is called
Acceleration
Two factors affecting Kinetic Energy are
Speed and Mass
Examples of potential energy
Roller coaster at its highest point ready to drop.
skier at the top of a mountain
bow extended back to release arrow
Food being digested in your body is an example of what type of energy?
Radiant Energy
Chemical Energy
Chemical Energy
You are trying to open a jar of pickles, and the lid is stuck. You have exerted alot of force on the lid,but it does not open?
Are you doing any work?
No, the lid did not move
An object‘S change in position relative to a reference point is called
Motion
Increase in velocity is called
Positive acceleration
What is stored Up energy is called?
Potential Energy
Two types of potential energy are called?
Gravitational Potential Energy
Elastic Potential energy
In order for motion to occur you need to have ......
Energy
What two factors affect how much work is being done?
Force and Distance
The distance traveled divided by total time taken to travel is called
Speed
Decrease in velocity is called
Negative acceleration or deceleration
Example of kinetic energy?
Moving car
runner
ball moving through the air
The energy is stored as result of gravity and pull of the earth is called?
Gravitational Potential Energy
The push or pull of an object is called
Force
What is the work formula?
Work = Force x Distance
Average Speed Formula is Total Distance / Total Time
The total distance that Josh traveled was 360 Km and it took him 4 hours to travel. What is his average soeed?
360km/4hours =90km/h
Average Acceleration = final velocity - initial velocity divided by the time it takes to change velocity.
Vf - Vi / t
A cyclist is starting to ride her bike at 2m/s south. AFTER ten seconds, her velocity is 7m/s south. What is her average acceleration?
7-2/10=5/10=.5m/s2
A girl with mass of 100kg is jogging at a speed of 5 meters per second.
kg x Mx m2/s2 =1joule
1/2 x 100kg x (5m/s)2
1/2 x 100 x 5m/s2
1/2 x 500 m/s2
What is the final step?
250 m /s 2 = 250 Joules
A trampoline is an example of what type of energy?
Elastic Potential Energy
Two factors that involve Force?
