What is speed?
The rate of change in position
100
What is work?
Work is the product of when a force is applied on an object and the object moves in the direction of the force
100
What is force?
The push or pull one body exerts on another
100
What is the difference between Scalar and Vector quantities?
A vector quantity uses both magnitude and direction and Scalar uses just magnitude

Susanna is riding her horse and it is traveling at 100 km/hr. How many hours will it take to cover a distance of 750 km?
t=75 hours
200
What is acceleration?
The rate of change in Velocity
200
What is Power?
the rate at which you do work
200
What is an unbalanced Force?
A force with unequal magnitudes and opposite directions
200
What do you do to power to convert it from watts to horse power?
You divide the power in watts by 746 to get the power in horse power.

Jacoby has one another game of chess and his opponent is fed up. If Jacoby's opponent flips the chess board 1.5 m and he does 25J of work, What is the amount of force applied on the chess board?
F= 16.7N
300
What is air resistance?
The force from air that pushes an object up while it falls (what goes against gravity)
300
What is the difference between distance and displacement?
Distance is the total length of the path travelled and displacement is the length between point A and Point B

A piece of cake, of mass 250 grams, falls vertically down from Carter's hand during his birthday party. It experiences a 1 N force of air resistance. What is the net force acting on the sponge? If the sponge reached terminal velocity, what would be the force of air resistance?
Net Force =2.45N
The force of Air Resistance would also be 2.45N
400
What is terminal Velocity?
The constant speed that an object reaches in free fall.

Carson is on the hunt, chasing a turkey down. If the turkey has a mass of 10 kg and starts from rest but once it sees Carson it runs a distance of 4000 meters in 60 seconds, how much power was used?
p=1481.5
400
What is Net force?
The sum of the forces acting on an object
400
What is required to do work on an object?
Displacement
400
Which Line segments represent constant speed?
C-D

Lexi and Brynn are trying to move the new doghouse they bought for Mochi, Body, and Abby. If the new dog house weighs 78 kg and Lexi and Brynn are only able to move it .75m in 40s. How much power are they using on the dog house?
P=0.11watts

Lucy is parachuting out of her plane. If Lucy weighs 120 lbs and her parachute creates an air resistance of 200N of air resistance, What is her Net force?
334.5 N
500
What is the difference between mass and weight?
Mass is the measurement of matter in an object and weight is the measurement of how gravity acts on that mass.

Susanna is still on her horse but now she remembers she is allergic. She slows her horse down to a stop to get off but then she faints off her horse, which takes 4s. If Susanna falls from rest, has a mass of 110.2 lbs and her horse is 2 meters tall. What force does she hit the ground with.
12.5N of force
