Montez read that bobcats can reach speeds of up to 30 mi/h. What does the speed of a bobcat indicate?
a) The time it takes to reach its maximum speed
b) The total amount of time it travels in one direction
c) The distance it travels to move between two points
d) The distance it can travel in a certain amount of time
A rock is sitting on top of a hill. The rock suddenly begins moving down the side of the hill. Why did the rock begin to move?
a) An unbalanced force acted on the rock and caused it to move
b) A sudden change in gravitational force caused the rock to begin to move
c) A balanced force caused the rock to move, and then gravity kept it moving
d) An upward forced balanced the gravitational force, so the rock began to move
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. Which of the following must have been greater for Blair than for Aaron?
a) His maximum speed during the race
b) His average speed for the entire race
c) His speed for the last 100 m of the race
d) His initial speed for the first 100 m of the race
Your weight on the moon is about one-sixth of your weight on Earth. Why do you weigh less on the moon?
a) The moon has more gravity because it is smaller than Earth
b) The moon has more gravity because it is closer to Earth than the sun
c) The moon has less gravity because it has less mass than Earth
d) The moon has less gravity because you are closer to its center than on Earth
Two airplanes are flying in the sky in such a way that the gravitational attractions between them decreases. Which statement best describes how the planes must be flying?
a) Away from each other
b) Next to each other at the same speed
c) Towards each other

b) Electrical
c) Mechanical
d) Normal
Which statement about the universality of gravity is false?
a) Any two objects that have mass also have a force of gravity acting between them, no matter how far apart they are.
b) The gravitational force between two objects depends only on their masses.
c) The gravitational force between two objects increases if mass is added to one object.
d) The gravitational force between two objects increases if the objects move closer together.
Which forces below act at a distance?
a) Magnetic, gravitational, electrical
b) Contact forces and non-contact forces
c) Magnetic, electromagnetic, contact forces
d) Non-contact forces such as hitting a ball with a bat

a) Acceleration
b) Friction
c) Gravity
d) Inertia
