Which of the following statements is true for an object moving at constant velocity?

• The object must have a net force acting on it

• The object must be accelerating

• The object has zero acceleration

• The object is speeding up

A student walks 4 meters east, then 3 meters west. What is true about the student’s motion?

• The displacement is 7 meters

• The distance is 1 meter

• The displacement is 1 meter

• The distance is 0 meters

A ball is thrown straight up into the air. What is the velocity and acceleration of the ball at the very top of its motion?

• Velocity = 0, Acceleration = 0

• Velocity = 0, Acceleration = downward

• Velocity = upward, Acceleration = downward

• Velocity = downward, Acceleration = 0

A box is sliding across a frictionless surface at a constant velocity. What is the net force acting on the box?

• Zero

• Equal to its weight

• In the direction of motion

• Opposite to the direction of motion

A person pushes a wall with a force of 100 N. According to Newton’s Third Law, what is the force the wall exerts on the person?

• 0 N, because the wall doesn’t move

• Less than 100 N, because the wall is stronger

• Exactly 100 N, in the opposite direction

• More than 100 N, to resist the push

An object is experiencing a net force but not moving. Which of the following is true?

• The object must be accelerating

• The object must be at rest with balanced forces

• The object must be in equilibrium

• The object could be in contact with a surface with friction or tension holding it

Which of the following statements about mass and weight is correct?

• Mass changes depending on location, weight does not

• Weight is a measure of inertia

• Mass is a force, weight is not

• Weight is the gravitational force acting on an object's mass

A block hangs from a rope and remains at rest. Which of the following statements is correct?

• The tension in the rope is greater than the weight of the block

• The rope exerts no force if the block is not accelerating

• The tension in the rope equals the weight of the block

• The block must be accelerating downward due to gravity
