Which of the following statements applies to the motion of a ball tossed upward?
I. It has constant acceleration on the way up
II. It has constant acceleration at the top of its path
III. It has constant acceleration as it moves downward.
I only
I and III
III only
All are correct
Which object would fall with greater acceleration in a vacuum - leaf or pebble?
The leaf
The pebble
Difficult to determine without more information
Both accelerate at the same rate
If you throw a ball straight up, what is its velocity at the highest point?
9.81 m/s2
0.0 m/s2
9.81 m/s
0.0 m/s
A ball is tossed upward and caught at the same position of throw. In the absence of air resistance, the speed of the ball when it is caught would be
less than the speed it had when tossed upwards
the same as the speed it had when tossed upwards
more than the speed it had when tossed upwards
What happens to the velocity of a ball as it is dropped off a cliff?
It decreases at a uniform rate
It increases at a uniform rate
It is constant
It increases at a non-uniform rate
What values are always known for a free falling object?
d = -9.8 m vi = 0 m/s
vi = -9.8 m/s a = -9.8 m/s2
vi = -9.8 m/s a = 0 m/s2
vi = 0 m/s a = -9.8 m/s2
An object falls from the top of a building that is 25 m high. Air resistance is negligible. What is the speed of the object when it hits the ground?
10m/s
25m/s
22m/s
65m/s
An object is thrown upwards with a speed of 14 m/s. How high does it go?
5m
10m
15m
20m
The object that was thrown upwards with a speed of 14 m/s . how much time is spent in the air?
2.8s
14s
7s
1.4s
Which of these graphs correctly illustrates freefall?
A
B
C
All could be correct
