Gravity
1. This is the acceleration of gravity on Earth.
What is -9.8 m/s2 or -10 m/s2?
6. This is the simple definition of a projectile.
What is an object with only the force of gravity acting on the object?
11. This is the reason an object could have a negative acceleration.
What is the object could be traveling in a negative direction?
16. This is the definition of velocity.
What is the displacement of an object over a given time period?
21. This is how far an object travels from its starting point.
What is the object's displacement?
2. When an object is thrown straight up into the air, this is the direction of the acceleration of the object.
What is down or toward the Earth?
7. An airplane is an example of a projectile: true or false.
What is false?
12. This is the simple equation to calculate acceleration.
What is a=(vf-vi)/t or a=ΔV/t?
17. This is the equation to solve for velocity.
What is v=d/t?
22. This is how far an object travels in total.
What is the object's distance?
3. This directly affects the force and acceleration of gravity on a planet.
What is the mass of the planet?
8. A bullet is an example of a projectile: true or false.
What is true?
13. A car took 10 seconds and 100 m to stop. This was the initial velocity of the car.
What is 20 m/s?
18. This is the velocity of a bear that runs 20 m in 1 second to save its cub from falling off a cliff.
What is 20 m/s?
23. This is the reason a parachute is not a projectile.
What is the parachute has more than the force of gravity acting on it?
4. If a bullet is dropped from 1 m off the ground and a bullet is fired horizontally from 1 m off the ground, this bullet will hit the ground first.
What is both will hit the ground at the same time?
9. When a projectile is shot at an angle upwards, this is the acceleration of the projectile on its path up.
What is -9.8 m/s2 or -10 m/s2?
14. This is the reason the acceleration of gravity on Earth is -10 m/s2.
What is the mass of the Earth?
19. This is the starting or beginning velocity of an object in a physics problem.
What is the initial velocity or vi?
24. This is the reason the acceleration of gravity is always negative.
What is the acceleration of gravity is always pulling down?
5. If you dropped a ball from a 10 m tall bridge, this is how long it would take the ball to hit the ground.
What is 1.4 seconds?
10. If an empty car rolled off a cliff 50 m high with an initial velocity of 50 m/s, this would be how far from the bottom of the cliff the car would land.
What is 158 m?
15. This is the acceleration of a car that goes from 0 m/s to 100 m/s is 7 seconds.
What is 14.3 m/s2?
20. This is the ending or last velocity of an object in a physics problem.
What is final velocity or vf?
25. This is the reason time can never be negative in a physics problem.
What is time does not move backwards?
