Presentation transcript:

RED What was Galileo’s theory of objects falling? Which would hit the ground first a tennis ball or a bowling ball? (no air resistance) What is centripetal force? What is free fall? How does free-fall relate to weightlessness in space? How does air resistance affect the speed of falling objects?

BLUE What two factors make up orbital motion? What is terminal velocity? What happens when terminal velocity is reached? What unit represents weight? What unit represents mass? What is an orbit?

GREEN What is projectile motion? What two factors are used to produce projectile motion? What is an example of projectile motion? What typically causes the horizontal motion in projectile motion? What factors have to happen for there to be free fall? What is the formula to calculate momentum?

ORANGE What is inertia? What is Newton’s First Law of Motion? How does Newton’s First Law represent balanced forces? How does mass affect inertia? What is the force that opposes motion? What is an example of Newton’s First Law of Motion?

PINK What is the unit of force? What is the unit for acceleration? What is Newton’s Second Law of Motion? What is the formula that represents Newton’s Second Law of Motion? What is the relationship between force and mass when calculating momentum? What factors can increase air resistance?

PURPLE What is the reaction force of a book sitting on a table? What is Newton’s Third Law? What is an example of Newton’s Third Law? How does Newton’s Third Law represent The Law of Conservation of Momentum? What happens when objects collide? What are the units for velocity?

YELLOW What is momentum? What is the Law of Conservation of Momentum? What is the relationship between velocity and momentum? A car rolls towards another car with a velocity 20 m/s east. Both cars have identical masses. What happens the total momentum after the two cars collide? Which Law of Motion is related to the Law of Conservation of Momentum? What is the relationship between mass and momentum?

BROWN How far does a car traveling 10 m/s go in 40 seconds? What is the momentum of a 20 kg object going 4.5 m/s north? What is the weight of a 15kg object on Earth? How much force is needed to cause a 50kg man to accelerate at a rate of 6.6 m/s2? How long will it take a bike traveling 30 m/s to go 10 meters? If you push on a 18kg buggy with a force of 4N, what will the cart’s acceleration be? A car decreases its speed from 4.8 m/s to 1.2 m/s as it goes up a ramp. What is the acceleration if it took 5.3s to get up the ramp? A ping pong ball rolls off a table and it takes 6 seconds for it to reach the ground. How fast was it traveling just before it hit the ground?
