1 - $100 The rate at which the object falls is due to what? gravity

1 - $200 What causes changes in motion that can be predicted and described. Unbalanced forces

All objects accelerate toward Earth at a rate 1 - $300 All objects accelerate toward Earth at a rate 9.8m/s2

1 - $400 For falling objects, what is the formula for changing velocity?

1 - $500 Bart Simpson decides to climb the Springfield water tower. He gets to the top and starts to walk around. He trips and falls off the tower. Ay Caramba! It takes him 3 seconds to hit the ground. What is his velocity when he hits the ground? 29.4 m/s downward

2 - $100 Galileo demonstrated in the 1500s that what does not impact how long it takes an object to fall to the ground? The object’s mass

2 - $100 What is the force that opposes the motion of objects through air? Air resistance

2 - $300 constant velocity that occurs when the force of air resistance is equal to the force of gravity. Terminal velocity

2 - $400 when no force other than gravity is acting on a falling object free fall.

2 - $500 the objects size, shape, and speed The amount of air resistance that a falling object experiences is determined by what three things? the objects size, shape, and speed

3 - $100 Any object traveling in circular path is constantly changing _________________. velocity

3 - $200 If you are inside of an object that is in a free fall, you will _________________. weightlessness

3 - $300 The unbalanced force that causes objects to move in a circular path is centripetal force

3 - $400 Centripetal means what? center seeking.

3 - $500 Orbiting objects have what 2 motions? they move forward and they are falling toward Earth.

4 - $100 the curved path an object follows when it is thrown near the Earth’s surface. projectile motion

4 - $200 Projectile motion has what 2 independent components? horizontal motion and vertical motion

4 - $300 Newton’s First Law of Motion states: that an object at rest remains at rest and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.

4 - $400 What is the tendency of all objects to resist any change in their motion or non-motion? Inertia

4 - $500 Newton’s Second Law of Motion states that the acceleration of an object depends on what two things? the mass of the object and the amount of force applied

5 - $100 What is inertia? The tendency of an object to resist a change in motion.

5 - $200 What keeps a projectile from moving in a straight path? gravity

5 - $300 Which of Newton’s Law of Motion relates to the experiment Balloon Racer? (explain why) 3rd

5 - $400 Which of Newton’s Law of Motion relates to the experiment Red Cup Drop? (explain why) 3rd

5 - $500 How does Newton’s 3rd Law of Motion explain how a person can walk across the floor? Foot pushes backward against friction and the person moves forward.

Final Jeopardy What “moon mission” tested Galleleo’s theory on falling objects? Apollo 15
