NEW UNIT!

STEPS:

1. TURN TO THE NEXT CLEAN PAGE IN YOUR JOURNAL

2. GLUE THE TITLE PAGE AND THE ANTICIPATION GUIDE IN

3. COMPLETE THE ANTICIPATION GUIDE. 4. BE READY TO TAKE NOTES

Questions to discuss:

How do forces affect the motion of an object? How do the laws of motion apply to every day life?

Unit 5 Force and Motion

Learning Goals (TEKS): Force, motion, and energy. The student knows that there is a relationship between force, motion, and energy. The student is expected to: 8.6B differentiate between speed, velocity, and acceleration 8.6A demonstrate and calculate how unbalanced forces

change the speed or direction of an object's motion 8.6C investigate and describe applications of Newton's law

of inertia, law of force and acceleration, and law of actionreaction such as in vehicle restraints, sports activities, amusement park rides, Earth's tectonic activities, and rocket launches

Sir Isaac Newton (1643 ? 1727)

One of the world's greatest scientists

Developed the 3 Laws of Motion

What is a Force?

A force is a push or pull When one object pushes or pulls another object, the first object is exerting a force on the second object Forces are described by strength and direction And are drawn with arrows

Forces are measured in Newtons

SI unit of force Symbol: N Measured by using a spring scale

There are two types of forces

Balanced Forces

(No change in motion) No Acceleration!

Unbalanced Forces

(Change in Motion) Acceleration!
