Inertia
Inertia causes your body to continue to move forward until stopped by your seat belt
What happens to your body when you slam on breaks?
Forces that work against motion
What are frictional forces?
An Unbalanced Force
What will move an object at rest?
It has changed position or place
How do you know an object had motion?
An action that can change the motion of an object
What is force?
Mass
What determines inertia?
Sliding, rolling, fluid, static
What are the four types of friction?
Every action has an equal and opposite reaction
What is Newton's 3rd Law?
A measure of speed in a given direction
What is velocity?
The combination of all of the forces acting on an object
What is net force?
Force
What changes inertia?
Friction was applied to the ball
Why does a ball eventually stop rolling on the ground?
Force = Mass x Acceleration
What do the letters represent in Newton's 2nd Law?
Running, cycling, jumping, swimming, eating
What are 5 examples of motion?
A newton
What unit is used to measure force?
Everything would fall apart
What if inertia didn't exist?
Thermal energy
What type of energy does friction produce?
To explain the relationship between a physical object and the forces acting upon it
What is the purpose of Newton's 3 Laws?
Issac Newton
Who developed the concept of motion?
Balanced forces are opposite in direction and equal in size while unbalanced forces are neither opposite nor equal
What is the difference between balanced forces and unbalanced forces?
All objects have inertia
Do we see inertia everyday?
Your hands will get warmer
What will happen if you rub your hands together?
Law of Inertia
What is Newton's 1st Law?
Force
What determines motion?
A force between any two objects
