Taryn is playing with a bouncy ball. She notices that the ball seems to travel faster on its way back toward the ground than on its way up into the sky. Why would the ball go slower moving away from the ground?

• because the ball must move against the force of Earth's gravitational field on the way up

• because the ball must move against the force of Earth's magnetic field on the way up

• because the ball moves with the friction force of air molecules on the way down

• because the ball moves with the elastic force of air molecules on the way down

• There are no downward forces on the book.

• The forces acting on the book are balanced.

• The forces acting on the book are unbalanced.

A teacher is demonstrating acceleration to his class by throwing two balls. He throws both balls using the same amount of force in the same direction. The first ball he throws has a mass of 0.1 kg and the second ball has a mass of 0.5 kg. Which statement BEST compares and describes the likely results of the demonstration?

• The first ball has a smaller mass, so it will have less acceleration than the second ball.

• The first ball has a smaller mass, so it will have greater acceleration than the second ball.

• The balls will have equal acceleration because they are being thrown in the same direction.

• The balls will have equal acceleration because they are being thrown with the same force.

Which argument is supported by the results of the investigation?

• The acceleration of an object is proportional to the mass of the object but not the force applied to it.

• The acceleration of an object is proportional to the force applied to the object but not the mass of it.

• The acceleration of an object is proportional to both the mass of the object and the force applied to it.

• The acceleration of an object is neither proportional to the force applied to the object nor the mass of it.
