8th Grade Physics Forces

Force A push or a pull. Image: http://gurtej.net/files/2010/04/man-pushing-a-car.jpg; Definition: www.thefreedictionary.com

Balanced Force 30N 30N The net force on an object is zero and the object’s motion does not change. (object is not moving or has constant motion) Image: http://image.wistatutor.com/content/force-laws-motion/balanced-force-example.jpeg; Definition: www.thefreedictionary.com

Gravity A force that pulls objects together. Gravity caused the apple to fall on Sir Isaac Newton’s head. Image from: http://4.bp.blogspot.com/_Qe1wgxDiEdU/S0Sufn6jbSI/AAAAAAAAAJo/ak9Ty7SfZr0/s400/newton2.jpeg; Definition adapted from: Access Science glossary, page 316.

Unbalanced Force 50N 20N The net force of an object is greater than zero which results in a change in the motion of the object. Image: http://image.wistatutor.com/content/force-laws-motion/unbalanced-force-example.jpeg; Definition: www.thefreedictionary.com

Net Force The sum of all the forces acting on an object. (The arrows that represent the forces are called Vectors) Image: http://zonalandeducation.com/mstm/physics/mechanics/forces/netForce/netf3.gif; Definition: www.thefreedictionary.com

Force is measured in NEWTONS The SI derived unit used to measure force is a NEWTON. One Newton is equal to the force needed to accelerate a mass of one kilogram one meter per second per second or 1 m/s2.

Calculating Net Force If forces are applied in the SAME direction, then the forces are ADDED together to find the Net Force. or

Calculating Net Force If forces are applied in the OPPOSITE direction, then the lesser force is SUBTRACTED from the greater force to find the Net Force and the object moves in the direction of the GREATER force. or

What is Motion? Motion is: A change in position of an object compared to a reference point

Forces affect Motion: They can make objects start moving. They can make objects move faster. They can make objects move slower. They can make objects stop moving. They can make objects change direction. They can make objects change shape.

Friction The force between objects that affects how easily they move past each other. Image: http://www.mikecurtis.org.uk/images/friction.jpg; Definition: Access Science glossary, page 315.

Friction affects Motion Friction is a force that causes objects to slow down or stop Image adapted from: http://sciencevault.net/11hscphys/84movingabout/pics/elevatedram.jpg; Definition: www.thefreedictionary.com
