Question
What kind of graph is the graph between kinetic energy and mass of the body?
- Straight line
- Exponential
- Linearly going up
- Horizontal straight line
Hint:
Straight line
The correct answer is: Straight line
K.E. = 1/2 mv²
If v is constant, K.E. is directly proportional to m
As v is constant, kinetic energy increases as mass increases.
Hence, the graph formed is a straight line.
