Motion
What is kinetic energy?
The formula for work.
What is work is equal to force times distance?
An object is in motion if it changes position relative to this.
What is a reference point?
What is the difference between speed and velocity?
What is speed has a direction?
This is a force that occurs when two surfaces make contact with each other as they are moving.
What is friction?
An example of work must have the motion of the object in the same direction as this other important variable.
What is the force on the object?
Draw a motion graph (distance vs. time) that shows constant speed.
What is a straight line with a slope?
What is the speed of a person walking 2 meters in 2 seconds?
What is 1 meter/second
The definition of Newton's First Law.
What is an object at rest stays at rest and an object in motion stays in motion unless acted upon by a force?
The formula for power.
What is power = work / time?
Draw a motion graph (distance vs. time) that shows an object at rest.
What is a straight line with no slope?
The velocity of a bicycle that traveled a total of 100 meters in 10 minutes going north.
What is 10 meters per minute north?
The acceleration of a car going a constant speed of 75 mph on the highway.
What is the car is NOT accelerating?
What is force = mass x acceleration?
The work done on a door when it moves a distance of 4 meters with a force of 10 Newtons.
What is the work done is 40 joules?
Draw a motion graph (distance vs. time) that shows positive acceleration.
What is a graph with a slope that curves upward?
Savannah sits on a couch at home for 2 minutes. She walks to the kitchen at a constant speed to make a snack, which takes 5 minutes. Draw Savannah's distance time graph.
What is a straight line with no slope, and then a straight line going up with a positive slope.
The acceleration of a bicycle that started at the top of a hill with a speed of 4 m/s and ended at the bottom of the hill with a speed of 8 m/s if the entire ride took 2 seconds.
What is 2 meters per second squared?
This is Newton's Third Law of Motion.
What is every action has an equal and opposite reaction?
The power of a lion as it does 42 joules of work in 7 seconds.
What is 6 watts?
