Unlike acceleration and velocity, speed does NOT need to specify

• direction.

• distance.

• mass.

• time.

Velocity can only be described by including both

• speed and direction of the object in motion.

• mass and direction of the object in motion.

• speed and volume of the object in motion.

• mass and volume of the object in motion.

The picture shows a ball rolling up a ramp. Which statement best describes the motion of the ball?

• The ball's speed is increasing.

• The ball's speed is decreasing.

• The ball's motion is constant.

• The ball's motion is stopping.

Ricardo came up with three different designs for paper airplanes. He would like to find out which design flies the farthest. Ricardo plans to fly each paper airplane five times. What step should Ricardo take after he flies each plane?

• Estimate which plane flew the farthest.

• Measure the distance that the plane flew and record it.

• Weigh the plane using a balance.

• Record the direction the plane turned before it landed.

Todd and Angela set up a ramp and released several cars from the top. If Todd and Angela want to determine the average speed of their cars down the ramp, what information do they need?

• acceleration from rest and distance down the ramp

• distance down the ramp and time down the ramp

• time down the ramp and acceleration from rest

• direction of motion and time down the ramp

A water rocket uses an amount of water and pressurized air to send a plastic rocket several feet into the air. As the water and air rush out the tail end of the rocket, the rocket shoots into the air. Which statement explains the rocket's motion?

• The inertia of the water and air must be overcome.

• The force of gravity of the rocket is greater than the water.

• The force of gravity must be overcome to achieve lift.

• For every action there is an equal and opposite reaction.

The picture shows Haile's paper airplane flying through the air. Haile's plane travels forward for a few feet and then begins to fall. What would explain the plane's ability to travel forward for a few feet without falling?

• The speed of the plane is equal to the speed of the oncoming air that pushes on the plane.

• The speed of the plane is greater than the speed of the oncoming air that pushes on the plane.

• The force of the air pushing up on the plane is equal to the force of gravity pulling down on the plane.

• The force of gravity pulling down on the plane is greater than the force of the air pushing up on the plane.

Eileen studies the types of forces on a steel ball. She begins by drawing a force diagram for the ball when it is not moving. Her drawing is given below.

When are the forces acting on the steel ball balanced?

• when it is moving

• when it is accelerating

• when it is slowing down

• when it is not moving

A student tries to push a bookshelf across a room. She applies as much force as possible, but she cannot make the bookshelf move. Which statement BEST describes why the bookshelf does not move?

• The student does not apply enough force to the bookshelf, so the forces are unbalanced.

• The student does not apply enough force to the bookshelf, so the forces are still balanced.

• The student applies too much force to the bookshelf, and now the forces on the bookshelf are balanced.

• The student applies too much force to the bookshelf, and now the forces on the bookshelf are unbalanced.
