100
The two measurements necessary for calculating average speed.
What is distance and time
100
A horse gallops a distance of 10 kilometers north in a time of 30 minutes. Its average Velocity would be
What is 20 Km/h north
100
A hokey puck is set in motion across a frozen pond. If ice friction and air resistance are neglected, the force required to keep the puck sliding at constant velocity is:
What is zero.
100
An object at rest near the surface of a distant planet starts to fall freely. if the acceleration there is twice that of the Earth, its speed one second later would be
What is 20 m/s.
100
If an object moves with constant acceleration, its velocity must
What is change by the same amount each second
200
If a freely falling object were somehow equipped with a speedometer, its speed reading would increase each second by about
What is 10 m/s
200
While a car travels around a circular track at a constant speed, its velcity
What is changes
200
A car accelerates at 2 meters/s/s. Assuming the car starts from rest, how far will it travel in 10 s?
What is 100m
200
In each second of fall, the distance a freely falling object will fall is (Increasing/Decreasing/The same)
What is increasing.
200
An object covers a distance of 8 meters in the first second of travel, another 8 meters during the next second, and 8 meters again during the third second. Its acceleration in meters per second per second is approximately
What is zero
300
An apple falls from a tree and hits the ground 5 meters below. It hits the ground with a speed of about
What is 10 m/s.
300
While an object near the Earth's surface is in free fall, its
What is velocity increasing
300
Disregarding air resistance, objects fall with constant
What is acceleration
300
An object falls freely from rest on a planet where the acceleration due to gravity is twice as much as it is on Earth. In the first 5 seconds it falls a distance of
What is 250 m.
300
At one instant a heavy object in air is moving upward at 50 meters per second. One second later its speed is approximately
What is 40 m/s
400
One half second after starting from rest, a freely falling object will have a speed of about
What is 5 m/s
400
If a car accelerates from rest at 2 meters per second per second east, its velocity 3 seconds later will be about
What is 6 m/s east.
400
A ball tossed vertically upward rises, reaches its highest point, and then falls back to its starting point. During this time the acceleration of the ball is always (in the direction of motion, opposite its velocity, directed downward, directed upward)
What is directed downward
400
At one instant an object in free fall is moving downward at 50 meters per second. One second later its speed should be about
What is 60 m/s
400
If a projectile is fired straight up at a speed of 10 m/s, the total time to return to its starting position is about
What is 2 s
500
An apple falls from a tree and hits the ground 5 meters below. It hits the ground with a speed of about
What is 10 m/s.
500
ball is thrown upwards and returns to the same position. Compared with its original velocity after release, its velocity when it returns is about
What is the same speed opposite direction.
500
Drop a rock from a 5-m height and it accelerates at 10 m/s2 and strikes the ground 1 s later. Drop the same rock from a height of 2.5 m and its acceleration of fall is about
What is the same amount.
500
It takes 6 seconds for a stone to fall to the bottom of a mine shaft. How deep is the shaft?
What is 180 m
500
Consider drops of water that leak at a steady rate from a dripping faucet. As the drops fall they
What is get farther apart
