This is a force of attraction between two objects due to their masses
What is gravity?
100
This is newtons third law of motion
What is every action has an equal and opposite reaction.
100
This moving energy
What is kinetic energy?
200
This can be a change in speed or direction or both
What is acceleration?
200
An example of this force is rubbing your hands together
What is friction?
200
This is the difference between mass and weight
What is mass is how much matter something has and weight is the force generated by the gravitational attraction of the earth ?
200
This is Newtons second Law
What is Force= mass x acceleration
200
This is the scientific definition of energy?
What is the ability to cause change?
300
This indicates both the speed and direction and object is moving
What is velocity?
300
This is a non contact force that holds us on Earth
What is Gravity?
300
True or false gravitational force is weaker between objects that have small masses.
What is true?
300
This is Newton's First law of motion
What is an object at rest will stay at rest, an object in motion will stay in motion until contacted by an unbalanced force
300
This is mechanical energy.
What is the total of kinetic and potential energy?
400
You will be directed to a time distance graph
you will need to identify the the object traveling at constant speed
What is B
400
When an object is at rest its forces must be this
What is balanced?
400
This is the universal law of gravity
What is all objects attract each other through gravitational force. The strength of the force depends on the masses involved and the distance between them?
400
A baseball accelerating faster than a softball is and example of this law
What is Newton's second Law of Motion

Blair and Aaron competed in a 400 m running race. Blair finished the race in 55 s and came in first. Aaron finished the race in 58 s and came in second. This must have been greater for Blair than for Aaron? A. maximum speed during the race B. Speed for the last 100m of race
C.average speed for the entire race D. initial speed for the 1st 100 m of the race
What is B?
500
A vector is used to describe velocity these are the factors a vector represents
What are direction and size?
500
These two factors determine the force of gravity
What is mass and distance between two objects?
500
When gravity is the only force acting on an object the object is said to be in this
What is free fall?
500
This is inertia.
What is then tendency of an object to keep doing what it is doing
500
Two identical space probes are orbiting Jupiter. Scientists determine that one of the space probes has a larger gravitational force acting on it than the other. This is the most likely reason for the difference A. One space probe reached Jupiter before the other B. One space probe has more air resistance than the other. C.Only one space probe is exerting a gravitational force on the other. D. One space probe is closer to Jupiter than the other
