Which of Newton’s Laws states that Force = Mass times acceleration?
Second Law of Motion
None of the above
Third Law of Motion
First Law of Motion
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
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.
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 before the car does and slides off the back
The penny stops just like the car, showing Third Law
Which of Newton's Laws says that an object at rest will stay at rest?
Third Law of Motion
Second Law of Motion
First Law of Motion
None of the above
What is the word to describe an object at rest tending to stay at rest? Hint: it means “laziness” or “inactivity.”
Inertia
Which of Newton’s Laws states that for every action, there is an equal and opposite reaction?
Second Law of Motion
None of the above
First Law of Motion
Third Law of Motion
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?
Speed and distance; called “rate”
Speed and direction; called “vector”
Force and direction; called “linear”
Mass and acceleration; called “scalar”
Newton’s 3 Laws of Motion explain about how __________ move.
Objects
Heat
Electrons
Electricity
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?
The rocket moving was the action, the breath was reaction
The breath was the action, the rocket moving was reaction
None of the above
The straw was the action, the rocket was the reaction
True or False: when a hammer hits a nail, the nail exerts an equal and opposite force on the hammer.
False
True
According to Newton's Second Law, if you push a wheelbarrow full of wood, you need ________force than if you push an empty one.
more
less
the same
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
Newton developed a formula to describe how gravity affects all matter. The 2 factors that are important in this law are:
Distance from each other & the time to travel between the 2
The length and width of each object.
The mass of each object & how far away from each other
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 bowling ball would fall faster.
They would fall at the same time
The feather would fall faster.
True or False: Acceleration is only when you speed up.
False, acceleration is speeding up, slowing down, or changing direction
Which of Newton's Laws of Motion says that an object in motion will stay in motion unless a force acts upon it?
Third Law of Motion
Second Law of Motion
First Law of Motion
None of the above
