Question

1. Match the first column with appropriate entries in the second and third columns and remake the table.
S. No. Column 1 Column 2 Column 3
1 Negative acceleration
The velocity of the ob-
ject remains constant A car, initially at rest
reaches a velocity of 50 km/hr in 10 seconds
2 Positive acceleration
The velocity of the object decreases
A vehicle is moving with a velocity of 25 m/s
3 Zero acceleration
The velocity of the object increases
A vehicle moving with the velocity of 10 m/s, stops after 5 seconds.

Answer 1

Answer:

1. Negative acceleration - The velocity of the object decreases - A vehicle moving with the velocity of 10 m/s, stops after 5 seconds

2. Positive acceleration - The velocity of the object increases - A car, initially at rest  reaches a velocity of 50 km/hr in 10 seconds

3. Zero acceleration - The velocity of the object remains constant - A vehicle is moving with a velocity of 25 m/s
