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

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

1 - $300 All objects accelerate toward Earth at a rate 9. 8 m/s 2

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! n It takes him 3 seconds to hit the ground. What is his velocity when he hits the ground? n n 29. 4 m/s downward

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

2 - $200 • What is the force that opposes the motion of objects through air? n Air resistance

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

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

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

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

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

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

3 - $400 n Centripetal means what? n center seeking.

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

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

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

4 - $300 n Newton’s First Law of Motion states: n 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 n What is the tendency of all objects to resist any change in their motion or non-motion? n Inertia

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

5 - $100 n Newton’s Third Law of Motion says ? n that for every action there is an equal and opposite reaction.

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

5 - $300 n Type question to appear here n Type answer to appear with a mouse-click here
