Motion and Forces ReviewUnit 5
Velocity Speed Velocity 50 Miles per hour 25 m/s 50 mph10 meters per second 50 miles per hour east 25 m/s towards home 50 mph left 10 meters per second up
Friction Occurs between all things in motion and contactAlways opposes motion Static > Kinetic Rolling < Sliding Slows things down.
Unbalanced Forces What would the result of forces on the box below be?
Newton’s 1st Law The law of inertiaNo change in motion will occur without an unbalanced force.
Average Speed S= d/t
Inertia The tendency of an object to remain at rest or in motionNewton’s 1st Law Depends on an objects mass but not velocity More massive objects have more inertia
Gravity Fundamental force of natureDepends on mass of objects and distance between them. If Gravity decreases, weight decreases If Gravity decreases, mass remains the same
Newton’s 3rd Law Law of Action-Reaction Action Force = Reaction ForceFor every action there is an opposite and equal reaction.
Newton’s 2nd Law Force = mass x acceleration F=maIf a toy car is pushed with a 5 N force and has a mass of 10 kg what will it’s acceleration be?
Momentum Momentum= mass x velocity p=mv
Effect of forces
Forces and Motion Demonstrate and calculate how unbalanced forces change the speed or direction of an objects motion.
FORCES Mrs. Cholak.
I. Motion – an objects change in position over time when compared to a reference point. A. Reference point- an object that appears to stay in place; building,
Forces & Motion Unit Vocabulary
Newton’s Laws Review. Name the Law What are the forces? Law: Forces: 1 st : Object at rest will stay at rest(balanced) 2 nd: F=ma (who has the most Newtons?)

Newton’s 2 nd Law. Enduring Understanding: Studying dynamics (causes of motion) has had a profound effect on the way humans view their world. Essential.
Newton’s Laws of Motion
Motion Chapter 8.1 Speed Velocity Momentum Speed Distance traveled divided by the time during which motion occurred.

Lecture 11: Laws of motion. Newton’s 1 st Law: Inertia Matter resists motion If at rest, it will stay at rest If in motion, it will stay in motion Mass.
FORCE. A FORCE IS A PUSH OR A PULL. IF FORCES ARE POWERFUL ENOUGH, THEY MAY RESULT IN MOTION. What is a force?
MOTION & FORCES CH d. motion: an object’s change in position relative to a reference point What is motion? How do you know the balloon moved?
