Describe the motion of a car driving down the freeway with no traffic using the words velocity, acceleration, and force.
The car has an increasing velocity. It has a forward acceleration and a forward force.
The car is moving with constant velocity. It has no acceleration and no force.
The car has a decreasing velocity. It has a backwards (negative) acceleration and backwards force.
Not enough information is given.
Describe the motion of a car making a u-turn using the words velocity, acceleration, and force.
The car has a constant velocity with no net force or acceleration.
The car has a constant velocity. Acceleration and force are directed towards the center of the turn.
The cars velocity is constantly changing because the direction is changing despite the speed staying constant. The acceleration and force are both directed to the center of the turn.
Not enough information is given.
Describe the motion of a car coming to a stop sign using the words velocity, acceleration, and force.
The car has a constant velocity with no net force or acceleration.
The car has a decreasing velocity. Acceleration and force are in the negative direction.
The car has an increasing velocity. Acceleration and force are in the positive direction.
Not enough information is given.
Describe the motion of a car making a turn on an icy road using the words velocity, acceleration, and force.
The car is moving at a very slow velocity with changing direction. The acceleration and force. are directed towards the center of the turn but both are very small due to low friction.
The car continues in a straight line with constant velocity. There is no force or acceleration.
The car has an increasing velocity. Acceleration and force are in the positive direction.
Not enough information is given.

Elmira, New York boasts of having the fastest carousel ride in the world. The merry-go-round at Eldridge Park takes riders on a spin at 18 mi/hr (8.0 m/s). The radius of the circle about which the outside riders move is approximately 7.4 m. Determine the time for outside riders to make one complete circle.
