5.P.1.4 #4: Schoolnet

Which best describes the speed of a ball as it is thrown straight up into

the air and comes back down?

• The ball goes up at a constant speed, stops, then comes down at a

  constant speed.

• The ball goes up at a constant speed, stops, and increases speed as

  it comes down.

• The ball goes slower and slower as it goes up, stops, and then goes

  faster and faster as it comes down.

• The ball goes slower and slower as it goes up, stops, and then comes

  down at a constant speed.

A student is pushing a box of books across the floor. The student stops, removes some of the books, and then continues pushing the box across the floor. Which best explains how removing some of the books affected the motion of the object?

• Removing some of the books reduced the mass of the box, and less force was

  needed to push it across the floor.

• Removing some of the books reduced the mass of the box, and more force was

  needed to push it across the floor.

• Removing some of the books did not affect the amount of force needed to push it

  across the floor.

• Removing some of the books decreased the mass of the box, and the same amount

  of force was needed to push it across the floor.

A plane carrying bags has a mass of 50,000 kg. After delivering the bags,

it has a mass of 30,000 kg. Which would best describe how the plane’s

motion would be affected on the way back?

• The plane would travel at a faster speed.

• The plane would travel at a slower speed.

• The plane would travel at the same speed.

Maria pulled an empty cart to the library. When she leaves the library, the

cart is full of books. How does the force of friction on the cart change?

• The force of friction increases because there is more mass.

• The force of friction decreases because there is more air pressure.

• The force of friction increases because the force of gravity decreases.

• The force of friction stays the same because Maria is still pulling the

  cart with the same force.

Team 1 and Team 2 each have five people who are pulling with equal

force on opposite ends of a rope. Which will most likely happen if Team 1

stops pulling on the rope?

• Team 1 will pull the rope closer to their side.

• Team 2 will pull the rope closer to their side.

• The rope will fall to the ground on both sides.

• The rope will continue to be pulled in both directions.

How does the mass of an object affect acceleration?

• The greater the mass of an object, the greater the force needed to

  accelerate the object.

• The greater the mass of an object, the smaller the force needed to

  accelerate the object.

• The smaller the mass of an object, the greater the force needed to

  decelerate the object.
