th 8 Grade Physics Changing Motion Unit
Force A push or a pull. Image: http: //gurtej. net/files/2010/04/man-pushing-a-car. jpg; Definition: www. thefreedictionary. com
Balanced Force 30 N The net force on an object is zero and the object’s motion does not change. Image: http: //image. wistatutor. com/content/force-laws-motion/balanced-force-example. jpeg; Definition: www. thefreedictionary. com
Unbalanced Force 50 N 20 N The net force of an object does not equal 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. Image: http: //zonalandeducation. com/mstm/physics/mechanics/forces/net. Force/netf 3. gif; Definition: www. thefreedictionary. com
Magnitude The strength of an object or event. Image: http: //www. supermantv. net/superman/images/wallpaper/super-strength. jpg; Definition: www. thefreedictionary. com
Speed The distance traveled by an object in a given amount of time. Image: http: //winstonmotorsports. com/images/bigstockphoto_Speedometer_At___Mph_291241. jpg; Definition: www. thefreedictionary. com
Velocity Speed + Direction
Acceleration You can FEEL acceleration. The rate at which an object’s speed and/or directions changes over time.

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.
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/_Qe 1 wgx. Di. Ed. U/S 0 Sufn 6 jb. SI/AAAAAJo/ak 9 Ty 7 Sf. Zr 0/s 400/newton 2. jpeg ; Definition adapted from: Access Science glossary, page 316.
Calculate To figure out by computation. Image: http: //www. myfhamortgageblog. com/wp-content/uploads/2009/05/calculator. jpg; Definition: www. thefreedictionary. com
Inertia The tendency of an object to resist a change in motion. Image: http: //blissfullydomestic. com/wp-content/uploads/inertia-251 x 300. jpg; Definition: www. thefreedictionary. com
Mass The total amount of matter in something. Image: http: //i. ehow. com/images/a 05/p 6/bc/do-determine-mass-ball-bearing_-200 X 200. jpg ; Definition: Access Science, glossary page 317.
Newton 15 N A measurement of force. Image: http: //cache 4. asset-cache. net/xc/200132441 -001. jpg? v=1&c=IWSAsset&k=2&d=5047 FA 587 DE 1 CADE 1 F 3073 D 2496 B 9401 EE 66 FA 52007 DD 989411803 DAC 64288 B 6 B 5 AF 9 B 7 D 601 FECA 8 ; Definition: www. thefreedictionary. com
Newton’s First Law The bowl will stay on the table until an unbalanced force acts on it. An object will stay in motion or an object will stay at rest unless acted upon by an unbalanced force. Image: http: //img. alibaba. com/photo/11518097/Coffee_Table_Design_Glass_Table_with_bent_glass. jpg ; Definition: www. thefreedictionary. com
Newton’s Second Law The smaller the object, the greater its acceleration, and the more force applied to an object, the greater its acceleration. Image: http: //www. physicsclassroom. com/class/newtlaws/u 2 l 3 e 3. gif; Definition adapted from: Science. Saurus page 284.
Newton’s Third Law For every action, there is an equal but opposite reaction. Image: http: //www. sciencetoymaker. org/balloon/images/newton. gif; Definition: www. thefreedictionary. com
Potential Energy at rest or stored energy. Image adapted from: http: //sciencevault. net/11 hscphys/84 movingabout/pics/elevatedram. jpg; Definition: www. thefreedictionary. com
Kinetic Energy in motion. Image adapted from: http: //sciencevault. net/11 hscphys/84 movingabout/pics/elevatedram. jpg; Definition: www. thefreedictionary. com
