Gravity
1. This is the acceleration due to gravity on Earth.
What is -9.8 m/s2?
6. When a projectile is shot at an angle upwards, this is the acceleration of the projectile in the y-direction.
What is -9.8 m/s2?
11. The units for acceleration are this when velocity is measured in meters per second and time is measured in seconds.
What are meters per second2?
16. This is the ending or last velocity of an object in a physics problem.
What is final velocity or v?
21. The acceleration in the x-direction of a horizontally launched object.
What is the 0 m/s2?
2. This is the reason the acceleration due to gravity is always negative.
What is the acceleration due to gravity is always pulling down?
7. The acceleration of an object for which u = v.
What is 0 m/s2?
12. There are the two things that can cause an object to accelerate.
What is a changing speed and changing direction?
17. This is the starting or beginning velocity of an object in a physics problem.
What is the initial velocity or u?
22. The initial velocity in the y-direction of a horizontally launched object.
What is 0 m/s?
3. 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?
8. The trigometric function we use to find the y-direction's initial velocity.
What is sine?
13. This is the simple equation (not a kinematic equation) to calculate acceleration.
What is a=(v - u)/Δt?
18. This is the simple equation (not a kinematic equation) to solve for velocity.
What is v=s/Δt?
23. The distance a ball travels in the x-direction when it is dropped from a 5 m table at a horizontal velocity of 10 m/s.
What is 10.10 meters?
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 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?
14. This is the acceleration of a car that goes from 0 m/s to 100 m/s in 7 seconds.
What is 14.3 m/s2?
19. This is the velocity of a bear that runs 60 meters in 4 seconds to save its cub from falling off a cliff.
What is 15 m/s?
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 159.7 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 1.43 seconds?
10. 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?
15. This is the acceleration of a car that goes from traveling at 50 mph down to 25 mph over 5 hours.
What is -5 miles per hour2 ?
20. This is the definition of velocity.
What is the displacement of an object over a given time period?
25. The initial horizontal speed of an object has this effect on the time the object spends in the air.
What is no effect?
