The three vehicles shown below are all traveling at a speed of 15 m/s, but only the pickup truck has a changing velocity. The pickup truck has a changing velocity because the pickup truck —
a)
can accelerate faster than the other two vehicles
b)
can accelerate faster than the other two vehicles
c)
is traveling on a curve in the road

a)
F The speed of the cart decreases as the cart rolls down the ramp because of friction between the cart and the ramp.
b)
The speed of the cart increases as the cart rolls down the ramp because the force acting on the cart is greater than the force of gravity
c)
The speed of the cart increases as the cart rolls down the ramp because the forces acting on the cart are unbalanced.
d)
The speed of the cart decreases as the cart rolls down the ramp because the forces acting on the cart are balanced.
4.
Two cars with different masses travel at the same speed down a hill toward a stop sign. What will happen when both cars apply brakes at the same time to stop?
a)
The car with the smaller mass will require less force to stop than the car with the larger mass.
b)
The car with the larger mass will maintain its velocity while traveling down the hill.
c)
The car with the smaller mass will take longer to stop than the car with the larger mass
d)
The car with the larger mass will have less inertia than the car with the smaller mass

6.
An object will continue moving in a straight line unless it is acted on by an unbalanced force. Which of the following best explains Earth’s motion?
a)
There is no unbalanced force acting on Earth because space is empty and nothing touches Earth.
b)
The gravitational force pulling Earth toward the sun is equal and opposite to the force pulling the sun toward Earth, so there is no unbalanced force acting on Earth.
c)
The sun moves in an elliptical orbit around Earth, and the sun’s gravity pulls Earth along.
d)
Earth moves in an elliptical orbit around the sun because the gravitational force of the sun attracts Earth.
