FORCES

How do forces move objects?

January 16, 2014

FORCES ARE:
• Any push or pull on an object
• Change the direction or motion of an object
• Stop, start, move, slow down, speed up, etc…
• May be seen or not seen
• Measured in Newtons (N)
NET FORCE(Balanced vs. Unbalanced):
• NET FORCE means:
• Total amount of force on an object
• Measured in Newtons still (btw 1 Newton= 0.2248089438741 pound)
• Balanced means:
• Total amount of force is ZERO (0) NEWTONS
• Object will not change its motion
• Unbalanced means:
• Total amount of force is NOTzero (0) Newtons
• Object will change its motion
FORCES AROUND US PICTURE(Left Hand Side)
• Pick a sport and draw a picture showing someone participating in it. (Drawings should be neat and colorful)
• Identify where forces are acting in the picture. Draw arrows to indicate where the force is coming from and where they are going
• Write 1 paragraph to answer the following questions:
• Why are forces important in the sport you chose?
• Give 2 examples of what would happen in your picture/sport if these forces weren’t present.
