Gravity
1. This is the acceleration of gravity on Earth.
What is -9.8 m/s2 or -10 m/s2?
6. 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?
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. The acceleration in the x-direction of a horizontally launched object
What is the 0 m/s^2?
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. The initial vertical velocity of a ball that is launched at a 30 degree angle with an initial velocity of 20 m/s
What is 10 m/s?
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 initial velocity in the y-direction of a horizontally launced object
What is 0 m/s?
3. This is the reason the acceleration of gravity is always negative.
What is the acceleration of gravity is always pulling down?
8. The horizontal initial velocity of a ball that is launched at a 30 degree angle with an initial velocity of 20 m/s.
What is 17.3 m/s?
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. A ball is dropped from a 5 m table at a horizontal velocity of 10 m/s. What is the range (distance) the ball traveled in the x direction?
What is 10.1 m/s?
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. The trigometric function we use to find the y-direction's initial velocity
What is sine?
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 u?
24. 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?
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. The acceleration of an object for which u = v
What is 0 m/s^s?
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 v?
25. the initial horizontal speed of an object has this effect on the time it spends in the air
What is no relationship?
