Forces and Motion Test Review

David and his friend Delia arrive at the playground. David and his friend are so much alike. They are the same age and the same height, but David weighs more than Delia. They can't wait to play on the new seesaw at the playground. David hops onto one side and Delia hops onto the other. What will most likely happen to David and Delia on the seesaw?

• David and Delia will not move because their forces are balanced.

• David and Delia will not move because their forces are unbalanced.

• David will move up, and Delia will move down because their forces are unbalanced.

• David will move down, and Delia will move up because their forces are unbalanced.

Look at the image below. Which statement provides the best description of the forces being presented?

• The tug of war game is balanced because they are all holding onto the rope.

• The tug of war game is unbalanced because the people on the left have more force than the man on the right.

• The tug of war game is unbalanced because the man on the right is more than the people on the left.

• The tug of war game is balanced because they are all having fun.

A fourth grade student wants to investigate how friction affects the motion of a ball rolling on different surfaces after rolling down a ramp.

• The ball rolling on the tile shows an unbalanced force since there was less friction than when the ball rolled on the carpet.

• The ball rolling on the carpet shows an unbalanced force since there was less friction than when the ball rolled on the tile.

• The ball rolling on the tile shows a balanced force since there was less friction than when the ball rolled on the carpet.

• The ball rolling on the carpet shows a balanced force since there was less friction than when the ball rolled on the tile.

Look at the image below of the player kicking the soccer ball. Which statement best supports the claim that gravitational force affects the motion of an object?

• The soccer ball flying up after the soccer player kicks the ball

• The soccer ball coming down after the soccer player kicks the ball

• The soccer ball has the same gravitational force as the soccer player

• The soccer ball have no gravitational force

A fourth grade student dropped an egg and feather at the same time. A classmate who was observing the experiment wrote down a claim about how the gravitational force affects the feather and the egg. Which statement best describes the relationship between gravitational force and the objects?

• The gravitational forces pulled the egg down faster because the feather is affected by air resistance.

• The gravitational forces pulled the feather down faster because it has less mass than the egg.

• The gravitational forces pulled the feather and the egg down at the same speed because they are equal masses.

• The gravitational force had zero effect on either object because they both fell.

Which argument best supports the image below?

• The basketball and tennis ball will hit the ground at the same time because of gravitational forces

• The basketball will hit the ground after the tennis ball because it is larger so it takes more time to fall

• The tennis ball will hit the ground after the basketball because the basketball has a higher mass

• The tennis ball will hit the ground before the basketball because it is smaller so it takes less time to fall.

Which of the following statements best supports the claim that gravitational force affects the motion of an object?

• Gravitational force is a natural phenomenon that only affects objects in space.

• Gravitational force pushes objects away from each other, making them float in the air.

• Gravitational force has no impact on objects on Earth; it only influences celestial bodies.

• Gravitational force pulls objects toward the center of the Earth, causing them to fall when dropped.

Tommy is at the zoo with his mother, father, and little sister. His sister is 12 years old and is in a wheelchair. Tommy wants to take his sister to go see the Gorilla exhibit but there are stairs. What statement best describes the usage of a simple machine to help Tommy and his sister see the gorillas?

• Tommy can ask his mother or father to help his sister push the wheelchair up the ramp

• Tommy can ask his sister to go down the slide.

• Tommy can ask his mother or father to climb the stairs

• Tommy can carry his sister up the stairs while in her wheelchair

Which of the following best describes how a pulley system changes forces when used to lift up an item?

• When the man pulls down on the rope to raise the object, the force is being transferred through the machine instead of having to lift the object by himself.

• The pulley acts like a second pair of hands and lifts the box on its own.

• The pulley uses force from the crate to pull the man down.

• The pulley allows for energy to be transferred from the person to the crate.
