You are standing on a street corner and see a bus moving at a rate of 6 m/s. You look closer and see a person walking to the back of the bus at a rate of 1 m/s. This is how fast that person appears to be moving.
What is 5 m/s?

Mr. Soller puts 100 kg of water at 20 degrees into a cup. The specific heat capacity of water is 4.2 J/g C. This is the final temperature of the water if 5000J of heat is added.
What is 32 degrees?

For Graph 1, this is the time interval when the object is traveling at the fastest positive velocity.
What is 2 to 4 seconds?

You are standing on a street corner and see a bus moving at a rate of 5 m/s. You look closer and see a person walking toward the front of the bus at a rate of 1 m/s. This is how much distance will they cover in 15 seconds relative to you.
What is 90 m?
200
An object moves 15.0 m right and then 11.0 m left. This is the distance traveled and displacement of the object.
What is distance = 26m, and displacement = 4 m right?

To raise the internal energy of a cup of coffee, you do 50 J or work by stirring. This is the amount of heat added if the total change in internal energy is equal to 200 J.
What is 150 J?

For Graph 2, this is the time interval when the object is traveling in a negative direction.
What is 15 - 40 seconds?

You are riding in a car that is moving at a rate of 8 m/s. A bus passes you going in the same direction, moving 9 m/s. This is how fast the bus appears to be moving relative to you.
What is 1 m/s?
300
This is the acceleration of an object that starts from rest and reaches a speed of 8 m/s in 2 seconds.
What is 4 m/s^2?
400
This is a law of nature that says heat tends to flow from warmer temperature objects to cooler temperature objects.
What is the 2nd law of thermodynamics?

This is the amount of water at 20 degrees Celsius that must be added to a 100 g cup of water at 90 degrees Celsius if the final temperature is going to be 75 degrees Celsius. The specific heat of water is 4.2 J/g C.
What is 27 g?

For Graph 3, this is the car that is accelerating at the fastest rate.
What is Car B?

Mr. Soller is driving down the highway at 60 mph. Someone else drives past him in the left lane, and it appears to Mr. Soller that they are moving at 20 mph relative to him. This is the speed of the other car.
What is 80 mph?

A bike accelerates from rest to a speed of 7.1 m/s over a time of 3 seconds. This is the distance covered by the bike during that time.
What is 10.65 m?

We have 2 objects that we put into a cup of water. Object 1 starts at 100 degrees and Object 2 starts at 80 degrees. If they both end with a temperature of 60 degrees, this is the temperature of the water.
What is 60 degrees?

On the moon, a feather is dropped from a height of 1.40 m. The acceleration of gravity on the moon is 1.67 m/s^2. This is the time it takes for the feather to fall to the surface of the moon.
