Force and motion practice

A push or pull that makes an object move, stop, change speed or change direction.

• motion

• force

• gravity

• friction

A type of force that pulls objects downward or towards one another.

• motion

• force

• friction

• gravity

The change in an objects position; movement.

• motion

• force

• inertia

• friction

A type of force that acts between two objects. It works in the opposite direction of an objects motion, slowing it down or stopping it.

• motion

• force

• friction

• gravity

Choose the BEST answer that describes how the mass of an object affects its motion.

• The greater the mass of an object, the slower the motion of the object.
• The greater the mass of an object, the faster the motion of the object.
• The greater the mass of an object, the greater the force to move the object.
• The greater the mass of an object, the greater the distance the object will travel.

If a ball is already moving and a new force is applied in the same direction the ball is moving, what will happen to the motion of the ball?

• The ball will keep moving at the same speed

• The ball will slow down

• The ball will speed up

• The ball will move backwards

Rose is sitting on the ground looking at an acorn. If no force is applied to the acorn, what will happen to motion of the acorn?

• The acorn will move forward

• The acorn will move backwards

• The acorn will blow away

• The acorn will not move

Use the table in the picture to answer this question.

Both objects in the table were given 10 Newtons of force. The objects are pushed along the same flat surface. Using the data from the table, what is the difference between object A and object B?

• Object A weighs more than object B

• Object B weighs more than object A

• Object B had more force than object A

• Object A had more force than object B

The table in the picture contains results of an experiment testing which object would travel the farthest when sliding down a ramp. Which object had the LEAST AMOUNT OF FRICTION while sliding down the ramp? 

• calculator

• checker

• pop cap

• quarter

A boy is pulling his little sister in a wagon. If his older brother comes along and they pull on the wagon together, how will this increase in force affect the motion of the wagon? 

• The wagon will speed up

• The wagon will slow down

• The wagon will keep going at the same speed and direction

• The wagon will remain at rest
