Friction and Gravity Quiz

What is friction?

• The resistance to motion that occurs between two objects in contact

• The force that causes objects to fall towards the ground

• The force that causes objects to move in a circular path

• The force that causes objects to move in a straight line

How does friction affect the movement of an object?

• It slows down the object's movement

• It speeds up the object's movement

• It has no effect on the object's movement

• It causes the object to move in a circular path

What is gravity?

• The force that causes objects to fall towards the ground

• The resistance to motion that occurs between two objects in contact

• The force that causes objects to move in a circular path

• The force that causes objects to move in a straight line

How does gravity affect the movement of an object?

• It pulls the object toward the ground

• It pushes the object away from the ground

• It has no effect on the object's movement

• It causes the object to move in a circular path

How does the mass of an object affect the force of gravity acting upon it?

• The greater the mass, the greater the force of gravity

• The smaller the mass, the greater the force of gravity

• The greater the mass, the smaller the force of gravity

• The mass of an object has no effect on the force of gravity acting upon it

What is air resistance?

• The force that opposes the motion of an object through air

• The force that causes objects to fall towards the ground

• The force that causes objects to move in a circular path

• The force that causes objects to move in a straight line

How does air resistance affect the movement of an object?

• It slows down the object's movement

• It speeds up the object's movement

• It has no effect on the object's movement

• It causes the object to move in a circular path

Which of the following objects would be affected the most by air resistance?

• A feather

• A bowling ball

• A pencil

• A car

Which of the following objects would be affected the least by friction?

• A hockey puck on ice

• A toy car on carpet

• A baseball on grass

• Marble on a smooth surface

How do friction and gravity work together to affect the movement of an object?

• Friction opposes the motion of an object, while gravity pulls it towards the ground

• Friction speeds up the motion of an object, while gravity pushes it towards the ground

• Friction causes the object to move in a circular path, while gravity pulls it towards the center

• Friction has no effect on the movement of an object, while gravity pulls it toward the ground.
