Newton's Laws
What does the First Law do?
The object will stay at rest, unless acted by an unbalanced force.
What is the combining of forces?
Net Force
How many types of friction is there?
Four main types
When a object changes its position
Motion
What is the formula to find force?
F=ma
What is the 3rd Law?
For every action there is an equal and opposite action
What does the Net Force cause?
Which one opposes the movement two contact surfaces that slide against each other
Sliding Friction
An indicator that orients you; the place from where you measure,record,or witness an event.
Reference Point
What is the formula to find Momentum
P=mv
What Is the 2nd law?
Force = mass times acceleration(F=ma)
Is the Force measured in Newtons?
True
Which one is when a ball rolls over a surface?
Rolling Friction
What is a Newton?
The unit used to measure force
Find the Force of 25kg as the mass and the acceleration 5m/s squared.
125N
Which one of them stays the same?
The 3rd Law
What force is not equal in size and opposite in direction
Unbalanced Forces
the tendency of an object to resist a change in motion
inertia
Find the Momentum with the mass of 35kg and 7m/s squared
245m/s squared
Which one has something called Inertia?
The First Law
Does a force not have more than one force that can act on an object at one time.
False
If there is no friction then it goes until it gets stopped by something on Static Friction
True
The force applied to a simple machine
Effort Force
What does the momentum transfer?
objects in a collision
