Do not copy what is up on the screen…think about your text language • I have tried to make the “notes material” red
What is weight? Pumpkin weighs 2,096 pounds
How do we measure the number of atoms in something?(How do we measure the mass?)
Which measurement depends on Earth?Which measurement is the same anywhere you travel?
WHAT do you need to know about the situation so you can answer yesterday’s question:
f = ma How much force does it take to make a bird explode?
f = ma forcemassacceleration
f = ma forcemassacceleration
What happens when two forces acting on each other are BALANCED?
Examples of balanced forces visible in this classroom?...look for systems where there is no motion…
How do Unbalanced forces in sports cause injuries?How can we prevent those injuries by understanding the forces involved?
How do Unbalanced forces in sports cause injuries?How can we prevent those injuries by understanding the forces involved? REMEMBER: - KINETIC energy = speed / motion - F = m a

3rd Law Equal and Opposite Reactions
What we learned last time: Gravity is dependant upon the mass of two objects and the distance between them. • If mass increases – Force of Gravity increases • If distance increases – Force of Gravity decreases. Jupiter has more mass than Earth; Therefore it has more gravity The satellite is farther from the center of Earth than we are; Therefore the planet is not pulling as hard on the satellite as the person standing on the surface!
What is Weight? • Definition: Weight is a measurement of how strongly gravity pulls on a mass. • Weight is completely dependent on the amount of gravity there is. • It the result of the force of gravity!!! • Without gravity there is NO WEIGHT (the ultimate diet plan!!!)
