Effects of Force and Motion

If an object is in motion and more force is applied to it, the object will begin moving ________. 

• FASTER
• SLOWER
• AT A CONSTANT SPEED

If two objects have the same mass and a greater force is applied to one of the objects, the object which receives the ____________ force will change speeds more quickly. For example if a ball is hit harder, it will speed up faster. 

• GREATER
• LESSER
• SAME

If an object must be slowed down quickly, the force applied to the object must be __________ than what is needed for a gradual slowing down.

• GREATER
• LESSER
• THE SAME

IS A PUSH OR PULL

• FORCE
• MASS
• SPEED
• GRAVITY

If a heavy (more massive) object is in motion, __________ force must be applied to get the object moving faster. 

• MORE
• LESS 
• THE SAME

 In order to slow down or stop a heavier (more massive) object, the force on that object must be __________ than for a less massive object. 

• GREATER
• LESS
• THE SAME

It is more difficult to change the direction of a _________ moving object, than one that is ________ in mass. 

• HEAVY, LIGHTER
• LIGHTER, HEAVY

If these boys are pulling with the same amount of force.  What will happen?

• They will not move at all.
• The boy in red will win.
• Both will fall down.

What happens when two forces act in the same direction?

• They cancel each other out.
• The stronger one prevails.
• Their strengths are added.
• Their sum divided by the two is the total force.
