What is Energy?
Energy is the ability to cause change.
100
What is a reference point?
It is a location to which you compare other locations.
100
what is acceleration?
the rate at which velocity changes.
100
What is a force?
It is a push or pull.
100
What is gravity?
A force of attraction between objects due to there mass.
200
What are the two types of energy?
Kinetic and Potential energy.
200
How is distance measured?
By using meters, kilometers, centimeters, miles, feet, or inches.
200
what is centripetal acceleration?
acceleration in circular motion.
200
Do balanced forces change motion?
No they do not.
200
An object traveling around another object in space is _________.
Orbit
300
What is Potential energy?
Potential energy is the stored energy that and object has due to its position, condition, or chemical composition.
300
How can you tell that motion took place?
By an objects position.
300
what is the difference between acceleration and centripetal acceleration?
centripetal acceleration is motion in circles, and acceleration is just regular motion.
300
How does inertia affect an object at rest?
The object at rest will stay at rest, so inertia has no affect on the object.
300
What two motions combine to produce orbit?
forward and downward motion.
400
What energies are occuring when an airplane is taking off?
A low amount of gravitational energy, and a high amount of kinetic energy.
400
What is the difference between speed and velocity?
Speed is how fast or slow something is going, and velocity has a specific direction that it is going in.
400
what will happen when acceleration and velocity are in the same direction?
the speed will increase.
400
Can forces occur in several pairs?
Yes they can occur in several pairs.
400
The gravitational attraction between two objects will ________ if one acquires more mass.
increases.
500
How is potential and kinetic energy alike?
Both energies have the ability to cause change.
500
What is the average speed when the distance is 17.6 meters and the time is 14.3 seconds? (speed= d/t)
1.2307692
500
true or false, if an object has low acceleration it is not moving very fast.
false
500
What is the equation to equal force?
F=ma
500
what is free fall?
it is when gravity is pulling it down and no other forces are acting on it.
