Newton’s Laws
(100 pts.) This law is often referred to as the “Law of Inertia”
What is Newton’s 1st Law?
The rate at which the position of an object changes.
What is velocity?
The North Pole of the Earth isn’t really the North Pole, but on the contrary…
What is the South Pole?
The product of an object’s mass and velocity
What is momentum?
This method of charging an object deals with “contact”
What is Conduction?
This law created the famous formula F=MA
What is Newton’s 2nd Law?
The rate at which an object’s velocity changes.
What is acceleration?
Opposites poles attract while like poles do this…
What is repel?
The symbol for a change in the momentum of an object…
What is Δp?
This is the opposite of Conduction
What is Induction?
This law states that for every action of force that occurs, there will always be an equal and opposite force/reaction.

This is equivalent to 1 Coulomb
What is 6.25 x 10¹⁸ elementary charges?
A 3kg crate is pulled across a horizontal surface by a 21 N force which gives the crate an acceleration of 2 m/s. Find: 1. The force due to friction 2. The coefficient of kinetic friction

A child riding her bike increases her speed from 2.0 m/s to 6.5 m/s in 15.0 secs. What was her acceleration during that time?
.30 m/s²
Field lines never do this…
What is cross/touch?
If an object has a greater change in momentum, and a greater impulse, that can only happen if there is…
What is the event in which a force is applied to an object for a longer period of time.
If field lines are drawn out from a positive charge, then when they are drawn into a charge, it is a
What is a negative charge?
