The Fine Define
Define Momentum
The measurement of how hard it is to change the inertia of an object
What is Newton's 1st Law also known as?
Law of Inertia
If Johnny pulls with 10 N of force of the rope, but Sally pulls 20 N, to what person will the rope go towards?
Sally
What is the formula for momentum?
momentum = mass x velocity
Define Net Force
The combination of all the forces acting on an object is called net force
F=MA
Newton's 2nd Law
If the spaceship is flying with 30 N of force, but the monster that has grabbed the ship with 31 N of force, will the spaceship get eaten?
Yes
What is the formula for speed?
speed = change in distance / change in time
Define Inertia
Matter's resistance to change in motion
Which law is the Law of Coupled Pairs?
Newton's 3rd Law also known as the Law of Action-Reaction
Kenny is pushing a box north at 100 N, but Freddy is pushing the same box north at 10 N. Which way will the box go?
(TRICK QUESTION) Both boys are pushing north, so the box will go north because it is being pushed by 110 N.
What is the formula for acceleration?
acceleration = final velocity - initial velocity / time
Define Speed
Distance traveled by an object in a given amount of time
Newton's 1st Law
Sidney is riding her bike down the road when the wind starts to blow. She tries to slow to a stop so she doesn't get blown over, but she finds herself being propelled forwards even faster. Why is this? And (if it applies) is it because of unbalanced or balanced forces?
It is because the wind was blowing at her back, pushing her forward, creating unbalanced forces.
What is the formula for finding force?
1N = 1kg x 1m/s2
