Question
Physics Question on Acceleration
The area of the acceleration-displacement curve of a body gives
A
impulse
B
change in momentum per unit mass
C
change in KE per unit mass
D
total change in energy
Answer
change in KE per unit mass
Explanation
Solution
The correct option is(C): change in KE per unit mass.
the area under the acceleration-displacement curve, when interpreted in terms of change in kinetic energy per unit mass, signifies how much the kinetic energy changes for each unit of mass as the object undergoes displacement.
