Answer the question truthfully. | Compare the motion of three cars. Which car was moving at the lowest speed? Choose from: a car that moved 130kilometers west in 5hours, a car that moved 485kilometers east in 5hours, a car that moved 460kilometers east in 5hours. | Look at the distance each car moved and the time it took to move that distance. The direction each car moved does not affect its speed.
Notice that each car moved for 5 hours. The car that moved 130 kilometers moved the shortest distance in that time. So, that car must have moved at the lowest speed. | [

Answer the question truthfully. | The objects are identical except for their temperatures. Which object has more thermal energy? Choose from: a 200-gram glass of apple juice at a temperature of 15°C, a 200-gram glass of apple juice at a temperature of 10°C. | The two glasses of apple juice have the same mass but different temperatures. Since the 15°C glass of apple juice is hotter than the 10°C glass of apple juice, it has more thermal energy. | [

Answer the question truthfully. | Vijay gives two friends a ride in his wagon. One friend sits in the wagon at a time. Vijay starts to pull the wagon across the yard. To move the wagon at the same speed each time, which friend does Vijay need to pull with a larger force? Choose from: a friend who weighs 21 pounds, a friend who weighs 28 pounds. | Look for the friend who is heavier.
A friend who weighs 28 pounds is heavier than a friend who weighs 21 pounds. So, to move the wagon at the same speed each time, Vijay needs to use a larger force to start moving the wagon with a friend who weighs 28 pounds. | [

Answer the question truthfully. | Isaac Newton was born in the 1600s and studied how objects move. He discovered three fundamental laws about forces and motion. According to Newton's third law, for every force, there is an equal and opposite force.
Consider the following force:

Answer the question truthfully. | The objects are identical except for their temperatures. Which object has more thermal energy? Choose from: a 4-kilogram block of copper at a temperature of 185°F, a 4-kilogram block of copper at a temperature of 260°F. | The two blocks of copper have the same mass but different temperatures. Since the 260°F block is hotter than the 185°F block, it has more thermal energy. | [

Answer the question truthfully. | Read the text about a person in motion.
Caleb rode an escalator from the first floor to the second floor of a shopping mall. Complete the statement. Assume that Caleb's mass did not change.
The gravitational potential energy stored between Caleb and Earth () as he rode the escalator. Choose from: increased, stayed the ... | Think about how the distance between Caleb and the center of Earth changed.
The second floor is higher than the first floor. As he rode the escalator toward the second floor, the distance between Caleb and the center of Earth increased. So, the gravitational potential energy stored between Caleb and Earth increased as ... | [
