Question

6. A small steel ball is dropped from a low balcony.
Ignoring air resistance, which statement describes its motion?
A It falls with constant acceleration.
B It falls with constant speed.
C It falls with decreasing speed.
D It falls with increasing acceleration.

Answer 1

Answer:

c) it falls with decreasing speed

Answer 2

A small steel ball is dropped from a low balcony. While ignoring the air resistance (A) it falls with constant acceleration.

Explanation:

1. If air resistance is negligible the free fall of an object experiences constant acceleration.
2. The gravitational field is constant due to the earth and it points towards the center of the earth.
3. But in general if an object dropped from a certain height it will take longer to reach the ground.
4. The time it takes to reach the ground depends on the initial height and the acceleration of the object.
