Newtons Laws 1
This is a measure of the change in the velocity or direction of a moving object.
One object pushing on another will always receive a push in return. True or false
True
What is Newton's first name
Issac
What happens when you push a swing really hard?
The swing will swing back with a lot of force
a tablecloth being pulled quickly from under dishes
Newton's 1st Law
Newton’s Second Law can be summarized using this equation
F=ma
(force=mass (x) acceleration)
What does the m stand for in F= ma
mass
This is required to overcome an object’s inertia
unbalanced force
If you jump on a trampoline, why does it bounce you back up?
When you push down on the trampoline, it pushes back up on you with the same force
This natural law states that for every action, there is an equal and opposite reaction
Newton's 3rd law
What causes a ball that has been kicked across the ground to stop?
Friction
A ball bounces away when another ball hits it. Which law does this demonstrate
Newton's 3rd law
When you stop quickly on your bike what term is used to explain why you fly forwards
Inertia
Why does a rocket fly when it launches? (or the frog fly)
The rocket pushes hot gases out the back, and the gases push the rocket forward
Which law? F=mxa
Newton's 2nd
If forces are canceled out, they are _________ forces
balanced
Objects with more mass are ______ to set in motion
harder
What external force helps keep a frisbee floating in the air
Air resistance
If you swim forward in a pool, what pushes you back?
The water pushes back on you as you push against it.
A car and a train are going the same speed. The car is easier to stop because of this
Less mass, less inertia
According to Newton’s Second Law, if the force increased but the mass remained the same, what happened
The objects acceleration increases.
This property of matter increases with its mass.
inertia
This is the measure of the force of gravity pulling down on an object of given mass
weight
Imagine you are playing tug-of-war. Why do you need to pull really hard if the other team is also pulling hard?
Because the other team's pull is an equal and opposite force to your pull
The Unit of force is this (weight is also measured in this)
