What is Three?
100
SI unit for force
What is a Newton (N)
100
In a game of tug-of-war, you pull the right at 100N and someone pulls to the left at 100N, this is the net force
What is 0N?
100
A push or a pull
What is Force?
200
This friction occurs when an object moves through air or water
What is Fluid Friction?
200
Newton's first Law is also called the Law of ___________
What is Inertia?
200
SI unit for mass
What is kilogram (or gram)?
200
Centripetal forces always pull this way
What is Towards the Center?
200
Force that pulls objects together
What is Gravity?
300
This friction occurs when a snake slithers on the ground
What is Sliding Friction?
300
Newton's second Law states that this depends on an objects mass and the forces acting on it
What is Acceleration?
300
SI unit for acceleration
What is m/s/s?
300
a 5 kg cat accelerates at 2 m/s/s, this is the net force acting on the cat
What is 10 N?
300
When the only force acting on an object is gravity
What is Free Fall?
400
Friction that occurs between two objects that are no moving
What is Static Friction?
400
Newton's third Law states that for ever action there is an __________ force in the __________ direction

SI unit for velocity
What is m/s2?
400
The acceleration due to gravity near Earth's surface
What is 9.8 m/s/s?
400
Force that causes objects to move in a circular path
What is Centripetal Force?
500
This type of friction is much easier to overcome than sliding friction to similar materials.
What is Rolling Friction?
500
To accelerate a 3kg skateboard at 9 m/s2, a force of this is needed
What is 3 Newtons?
500
Si unit for momentum
What is kg x m/s?
500
An object traveling in a circle is always accelerating because it is constant changing this
