Newton’s 3 Laws of Motion explain about how __________ move.
Objects
Electrons
Heat
Electricity
Which of Newton's Laws says that an object at rest will stay at rest?
First Law of Motion
None of the above
Second Law of Motion
Third Law of Motion
Which of Newton's Laws of Motion says that an object in motion will stay in motion unless a force acts upon it?
First Law of Motion
Second Law of Motion
None of the above
Third Law of Motion
Which of Newton’s Laws states that Force = Mass times acceleration?
First Law of Motion
Third Law of Motion
Second Law of Motion
None of the above
Which of Newton’s Laws states that for every action, there is an equal and opposite reaction?
Third Law of Motion
Second Law of Motion
First Law of Motion
None of the above
The paper rocket on a straw that we made in class showed Newton’s Third Law. Which was the “action” and which was the “reaction” in that experiment?
None of the above
The breath was the action, the rocket moving was reaction
The straw was the action, the rocket was the reaction
The rocket moving was the action, the breath was reaction
According to Newton's Second Law, if you push a wheelbarrow full of wood, you need ________force than if you push an empty one.
the same
more
less
True or False: when a hammer hits a nail, the nail exerts an equal and opposite force on the hammer.
False
True
When a toy car with a penny on top goes down a ramp, what happens to the penny when the car is stopped? And which Law does this demonstrate?
The penny keeps going past the car, showing the First Law
The penny stops just like the car, showing Third Law
The penny stops before the car does and slides off the back
What is the word to describe an object at rest tending to stay at rest? Hint: it means “laziness” or “inactivity.”
Inertia
If a penny is resting on an index card over a cup, and you flick the card away, what will happen to the penny and what force is acting upon it?
The penny will hover in mid-air, force is anti-gravity
The penny will fly off with the card, force is the flick
The penny drops into the cup, force is gravity
If you push an object such as a cart, first with little force, then again with more force, will the cart go faster the first time or the second time? Hint: F=MA
The cart will go faster the second time because the more force, the more acceleration
True or False: Acceleration is only when you speed up.
False, acceleration is speeding up, slowing down, or changing direction
Velocity has 2 pieces of information that it tells you. What are those 2 and what is the name for something that tells you 2 things?
Mass and acceleration; called “scalar”
Force and direction; called “linear”
Speed and distance; called “rate”
Speed and direction; called “vector”
T or F: According to Newton’s 3rd law of motion, in a car crash, if one car has more mass than the other, the amount of force that the smaller car exerts on the larger car is EQUAL TO what the larger car exerts on the smaller car.
True, Newton's Third Law is not affected by mass, but it's likely that the smaller car will have more damage.
In a vacuum (no gravity), such as space, would a bowling ball and a feather fall at the same time or would the bowling ball fall faster?
The feather would fall faster.
The bowling ball would fall faster.
They would fall at the same time
