Newton's Laws
This law states that: an object in rest stays at rest and an object in motion stays in motion unless acted on by an unbalanced force
What is Newton's First Law of Motion?
Answer with one of the three Laws:
If you were riding a bicycle, the second you apply the first push, you will keep moving in a straight line until someone or something stops you
What is Newton's First Law of Motion
The more force you put onto an object, the less it accelerates
What is FALSE
A measure of how fast an object is moving
What is speed?
In this formula: f=m*a, "m" stands for...
What is mass?
This law states that: the acceleration of an object depends on the mass of the object and the amount of force applied
What is Newton's Second Law of Motion?
Answer with one of the three laws:
If a boy with more mass and a girl with less mass are jumping on two different trampolines, the boy will need more force to have the same acceleration
What is Newton's Second Law of Motion
A feather falls faster than most other objects due to gravity
What is FALSE
(because the feather has more surface area and it is flat, friction in the air slows it down)
A measure of how fast an object is moving + what direction it is moving
What is velocity?
In this formula: f=m*a, "a" stands for...
What is acceleration?
This law states that: for every action, there is an equal or opposite reaction
What is Newton's Third Law of Motion?
answer with one of the three laws:
when you sit on a chair, you are pushing the chair down with a certain amount of force. the chair will then push the exact same amount of force back in the opposite direction so that you do not fall or break the chair.
Newton's Third Law of Motion
The less massive an object, the faster it accelerates
What is TRUE
A falling object that only has gravity acting upon it
What is free fall?
In this formula: p=m*v, "v" stands for...
What is velocity?
answer with one of the three laws:
if you are pushing a shopping cart filled with groceries and your friend is pushing an empty shopping cart with the exact same amount of force, the empty shopping cart will accelerate more quickly because it has a lower mass.
Newton's Second Law of Motion
If you drop a bowling ball and a golf ball at the same time from the same height, the bowling ball will fall faster because it is heavier
What is FALSE
(they will both hit the ground at the same time)
When an object is changing direction, speeding up, or slowing down
What is acceleration?
In this formula: p=m*v, "p" stands for...
What is momentum?
DOUBLE JEOPARDY!!!!
name the two laws that apply to this example: (double-jeopardy points only if you can also explain why the two laws apply)
when we throw a bowling ball, we cause it to move with a constant speed until it hits the pins and stops moving. the heavier the bowling ball, the more force that will be exerted on the pins.
Newton's First Law of Motion - constant movement until interrupted
Newton's Second Law of Motion - mass affects amount of force (f=m*a)
According to Newton's Second Law of Motion, if you jump on a trampoline with a force of 3 m/s, then the trampoline will also push back a force of 3 m/s
What is TRUE
The maximum speed of a falling object
is when force of gravity and force of air resistance balance each other
What is terminal velocity?
