Newtons Laws

3 of Newtons Laws

• Action Reaction
• F=MxA
• Inertia

Action Reaction

Action Reaction

• With every action, you apply a reversed force
• Example: When you jump you must push off the ground to go up

Inertia

Inertia

• An object in motion tends to stay in motion until an unequal force reacts slowing down the object which will then completely stop
• If you through a tennis ball at a wall, it stops; if you through a tennis ball in the air, gravity pushes it down and if you through it in an empty space, it will start to lose speed and fall on the ground
• The object can also change shape,color,speed etc

F=MxA

Force and Motion

• Balanced Force
• Force
• Friction
• Gravitational Potential Energy
• Gravity
• Inertia
• Kinetic Energy
• Potential Energy
• Speed
• Thrust
• Unbalanced Force

Acceleration
===========
The rate of change velocity; can mean speeding up, slowing down or changing direction

Air Resistance
===========
The frictional force between air and objects moving through it

Balanced Forces
============
Forces are equal but in opposite directions

Force
=====
A push or pull measured in Newton's

Friction
======
A force that opposes motion between two objects that are touching and causes an object to slow down or come to a stop

Gravitational Potential
Energy
=================
Energy that an object posses because of its position in a gravitational field

Gravity
======
An attractive force that exists betweenall objects that have mass;the greater the mass, the greater quantity of gravity between the object

Kinetic Energy
============
Energy in motion

Potential Energy
=============
Energy an object
has due to its position

Speed
=====
Determined by dividing the total distance by the total time it took to cover the distance

Thrust
=====
A pushing force that propelsobjects in the opposite direction

Unbalanced Forces
===============
Forces that are unequal and cause an object to accelerate

Velocity
======

Speed in a particular direction(70 mph E)
