SIR ISAAC NEWTONAND HIS LAWS OF MOTION

“IF I HAVE SEEN FURTHER THAN OTHERS, IT IS BY STANDING UPON THE SHOULDERS OF GIANTS.”

SIR ISAAC NEWTONDISCOVERED THE LAWS OF LIGHT, COLOR, MOTION,

AND GRAVITY

NEWTON’S LAWS OF MOTION

FIRST LAW: A BODY AT REST WILL REMAIN AT REST, AND A BODY IN MOTION WILL REMAIN IN MOTION AT A CONSTANT VELOCITY UNLESS ACTED UPON BY AN UNBALANCED FORCE.

SECOND LAW: THE ACCELERATION OF AN OBJECT DEPENDS UPON ITS MASS AND APPLIED FORCE. F=MA

THIRD LAW: FOR EVERY ACTION THERE IS AN EQUAL AND OPPOSITE REACTION.

NEWTON’S FIRST LAW OR MOTION

AN OBJECT STAYS AT REST UNLESS ACTED UPON BY AN UNBALANCED FORCE.

WHAT UNBALANCED FORCE IS ACTING ON THIS BAG?

WHAT FORCES ARE ACTING ON THIS COASTER CAR? WHICH FORCE IS STRONGER?

FORCE-- A PUSH OR A PULL

NET FORCE-- SEPARATE FORCES ADDED TOGETHER

UNBALANCED FORCE-- A FORCE THAT CHANGES AN OBJECT’S MOTION OR CAUSES IT TO ACCELERATE

GRAVITY-- THE FORCE OF ATTRACTION BETWEEN TWO OBJECTS

FRICTION-- A FORCE CAUSED WHEN TWO SURFACES SLIDE PAST EACH OTHER; SLOWS MOVING OBJECTS AND CONVERTS KINETIC ENERGY INTO HEAT (THERMAL ENERGY)

A BODY IN MOTION WILL REMAIN IN MOTION UNLESS...

SECOND LAW OF MOTION F=MA

A HEAVIER OBJECT REQUIRES A BIGGER FORCE (OR PUSH) TO

CHANGE ITS SPEED OR DIRECTION THAT A LIGHTER OBJECT IT IS MUCH EASIER TO PUSH START A SMALL CAR

THAN A BIG TRUCK.

MASS-- THE AMOUNT OF MATTER IN AN OBJECT; MEASURED IN GRAMS

INERTIA--AN OBJECT’S RESISTANCE TO CHANGE IN ITS STATE OF MOTION; RELATED TO AN OBJECT’S MASS

SPEED--DISTANCE TRAVELED PER UNIT TIME(I.E. MPH)

ACCELERATION--A MEASURE OF HOW QUICKLY THINGS PICK UP SPEED OR SLOW DOWN; CAUSED BY UNBALANCED FORCES

WHICH FALLS FIRST AND WHY?

FOR EVERY ACTION THERE IS AN EQUAL AND OPPOSITE REACTION

THIRD LAW OF MOTION

NAME THE ACTIONS AND REACTIONS YOU SEE IN THESE PICTURES. WHERE ARE THE FORCES BEING APPLIED?

1. Newton!s 1st Law

2. Newton!s 2nd Law

3. Newton!s 3rd Law

4. Force

5. Net force

6. Unbalanced force

7. Gravity

8. Friction

9. Mass

10. Inertia

11. Speed

12. Acceleration

a. A push or a pull

b. The amount of matter in an object; measured in grams

c. A body at rest will remain at rest and a body in motion will remain in motion at a constant velocity unless acted upon by an unbalanced force. AKA the Law

of Inertia

d. Distance traveled per unit time (i.e. mph)

e. A force that changes the direction or acceleration of an object!s motion

f. A force caused when two surfaces slide past each other; slows moving objects and converts kinetic energy into heat (thermal energy)

g. The force of attraction between two objects

h. For every action there is an equal and opposite reaction

i. Separated forces added together

j. A measure of how quickly things pick up speed or slow down; caused by unbalanced forces

k. F=ma The acceleration of an object depends upon its mass and applied force

l. An object!s resistance to a change in its state of motion; related to an object!s mass.
