PS Demon Time Review 9/2/21

Which force produces a change in motion?

• unbalanced force

• balanced force

• gravitational force

• combined force

It takes more force to accelerate the iron man on the left than the iron man on the right because the iron man on the left has more mass. This best describes

• Newton's first law, the law of inertia
• Newton's second law, the law of acceleration
• Newton's third law, the law of action reaction 
• The law of universal gravitation

The formula 
? = mass x acceleration
or 
? = m x a 
is used to find 

• Force
• Velocity
• Momentum
• Gravity

An automobile you are riding in suddenly stops, but you continue to go forward.

• Newton's
  1st
  Law of Motion
• Newton's
  2nd
  Law of Motion
• Newton's
  3rd
  Law of Motion

If an object is stationary (not moving) the forces acting upon it are _____________

• unbalanced
• weak
• balanced
• Hulk Smash!

What Newtons law does this picture represent

• Newtons 2nd law 
• Law of gravity 
• Newtons 1st law
• Newtons 5th law

The picture of the position vs. time graph shows an object that is...

• accelerating/speeding up
• moving at a constant speed 
• not moving 
• accelerating/slowing down. 

What is the standard unit force is measured in?

• Newtons
• pounds
• grams
• meters

Acceleration of an object happens when things ________

• slow down
• go faster
• change direction (turn)
• All of the above

LT4: The graph shows Ashley riding her bike to Maria's house. 
What is occurring from point A to point B?

• they are traveling at a constant speed
• they are decreasing in speed
• they stopped to take a break
