Gravity
WHAT HAPPENS TO THE FORCE OF GRAVITY BETWEEN 2 OBJECTS IF THE DISTANCE BETWEEN THEM INCREASES?
Decreases

3000N
AS THE ANGLE OF A RAMP INCREASES, THE COEFFICIENT OF FRICTION ____________________.
REMAINS THE SAME
THIS IS THE WEAKEST FUNDAMENTAL FORCE

WHAT HAPPENS TO THE FORCE OF GRAVITY BETWEEN 2 OBJECTS IF THE MASS OF 1 OBJECT INCREASES?
Increases
A 10kg block accelerates to the right at 5 m/s2. What is the net force on the block?
50 N
FRICTION ALWAYS GOES IN THIS DIRECTION
Opposite to the direction of motion
THIS FUNDAMENTAL FORCE IS RESPONSIBLE FOR FRICTION, TENSION, ELECTRICITY AND MORE
Electromagnetic

RUSSIA
IF AN 80kg MAN WEIGHS 128N ON THE MOON, WHAT IS THE ACCELERATION DUE TO GRAVITY ON THE MOON?
1.6 m/s2
A disk slides with a constant velocity. Are the forces balanced or unbalanced?
Balanced
MIKE PUSHES A 5N TIRE ACROSS AN ICY ROAD. WHAT IS THE FORCE OF FRICTION BETWEEN THE TIRE AND THE ROAD?
0.15*5N = 0.75 N
WHAT FORCES ARE ACTING ON A BALL IN FREE-FALL?
GRAVITY (and air resistance)
THIS IS THE HOTTEST PLANET IN OUR SOLAR SYSTEM
VENUS
WHAT IS THE DIFFERENCE BETWEEN MASS AND WEIGHT?
Mass = amount of matter, Weight = force of gravity on object
A rocket is launched and accelerates upward. What is the direction of the net force on the rocket?
WHAT IS THE DIFFERENCE BETWEEN STATIC AND KINETIC FRICTION?
Static - holds object at rest, kinetic - acts against moving object
WHAT IS THE NORMAL FORCE?
force of surface on object, perpendicular to surface
MYCOLOGY IS THE STUDY OF THIS EARTHY ORGANISM
MUSHROOMS
THE LAW THAT SAYS EVERY OBJECT IN THE UNIVERSE ATTRACTS EVERY OTHER OBJECT
Newton's Universal Law of Gravitation
A BUG HITS THE WINDSHIELD OF A CAR. USE NEWTON'S LAWS TO EXPLAIN WHY THE BUG GETS SQUASHED BUT THE CAR DOES NOT.
Same force, but bug has less mass...so more acceleration
