Newtons Laws
How many laws of motion does Newton have?
3
Mass changes, but weight never does. True or False
False
_____ is a property of moving objects that make it harder to stop
Momentum
If an object has a force of 240/ and a mass of 16 what is its acceleration
15
What was Newtons 1st name
Isaac
The earth has this much stronger gravity then the moon.
6x stronger. A person that weighs 17 pounds on moon, will weigh about 100 on earth.
Mass * Velocity = ________
Momentum
An object has a mass of 1400 KG and has a velocity of 7.5 M/s what is its momentum?
10,500 KG M/S
Newtons 2nd Law
A= F/M
Weight is labeled with what letter in the equation to find it using mass and acceleration
F
What is the conservation of momentum?
We do not lose or gain momentum in a crash, it is just transfers from 1 thing to the other.
What is the relationship called where one side increases and the other side decreases?
Inverse
Newtons 1st Law of Motion
Object at rest stays at rest an object in motion stays in motion unless it has a reason to change.
Earths gravity is consistent, which makes our weight consistent, what number to we use to represent earths gravity in an equation.
9.8
To calculate total momentum, you need to do _____ to the 2 things crashing into each other.
Add, Subtract, Divide, Multiply
Add
If an object has a mass of 67 KG and its acceleration is 9.8, what is its weight in Newtons?
657 or 656.6
Newtons 3rd Law of Motion
Every action, there is an equal and opposite reaction.
1 Newton = ______ Pounds
.225
Conservation of Momentum
If an object has a mass of 111 KG and its acceleration due to gravity is 9.8, what is its weight in pounds
245 or 244.75 pounds
