What is average velocity?
100
the average velocity of a golf cart that moves 550 meters in 100.0 seconds
What is 5.5 m/s?
100
the acceleration of a ball that is thrown upward then falls back to the ground
What is a constant -9.81 m/s^2? (g)
100
the displacement of a ball that is thrown upward 7.0 m and caught at the same height at which it was thrown
What is 0?
100
the sign given to acceleration when an object is thrown into the air
What is negative?
200
The value assigned to gravitational acceleration
What is -9.81 m/s2
200
the velocity of a ball as it is thrown up then comes back down
What is "decreases on the way up and increases on the way down"? (if you include that it stops at the top of its path that is correct, but not necessary to get the points for this question)
200
the acceleration of a car that goes from 15 km/h to 125 km/h in 18.0 seconds.
What is 1.77 m/s^2?
200
the upward displacement of a ball that is thrown straight up with an initial velocity of 22.0 m/s
What is 24.7 m?
200
the accleration of an object that is dropped compared to the acceleration of an object that is thrown downward
What is the same?
300
acceleration
What is the change in velocity over time?
300
the final velocity of a car that starts at 20.0 km/h and accelerates at 2.50 m/s2 for 15.0 seconds.
What is 43 m/s?
300
the acceleration of a dog that starts from rest and reaches a velocity of 9.25 m/s over a distance of 34.0 m
What is 1.26 m/s^2?
300
the displacement of a ball that is dropped from cliff and takes 7.50 s to reach the ground
What is -276 m.
300
where gravity exists
What is between any two objects that have mass?
400
the slope of a velocity vs. time graph
What is acceleration?
400
the initial velocity of a dog that runs 50.0 m while accelerating at 1.50 m/s^2 for 4.75 seconds.
What is 6.96 m/s?
400
the acceleration of a jet moving at 25.0 km/h that must reach a take off speed of 200.0 km/h on a runway that is only 200.0 m long.
What is 7.61 m/s^2?
400
At the edge of a cliff a ball is thrown straight up with a velocity of 21.0 m/s and lands with a velocity of 120 m/s. A second ball is thrown downward at 21.0 m/s from the same cliff. This value is the landing velocity of the second ball
What is 120 m/s?
400
tthe gravitational force on the mass of an object
What is an objects weight?
500
the quadratic formula
What is x = [ -b ± sqrt(b^2 - 4ac) ] / 2a
500
The final velocity of a bird that is flying at 8.44 m/s then accelerates at 2.03 m/s^2 for 80.0 m
What is 19.9 m/s?
500
the acceleration of a car that starts at 35.0 m/s and travels 75.0 m in 15.0 s
What is -4.00 m/s^2?
500
On Earth a ball is thrown straight up with a velocity of 11.0 m/s. The same ball was thrown upward at 7.0 m/s on the moon where the acceleration is about -1.6 m/s^2. This value is the difference between how high the ball would reach on the moon compared to Earth
What is 9.21 m higher on the moon?
500
the two quantities that are needed to determine the force of gravity between two objects
What are mass and distance between the objects?
