Answer:
n the case of linear motion, the change occurs in the magnitude of the velocity, the direction remaining constant.
In the case of circular motion, the magnitude of the velocity remains constant, the change in its direction occurring.
Explanation:
Velocity is a vector therefore it has magnitude and direction, a change in either of the two is the consequence of an acceleration on the system.
In the case of linear motion, the change occurs in the magnitude of the velocity, the direction remaining constant.
= (v₂-v₁)/Δt
In the case of circular motion, the magnitude of the velocity remains constant, the change in its direction occurring.
= v2/R
In the general case, both the module and the address change
a = Ra ( a_{t}^2 + a_{c}^2)
Answer:
All living organisms have complex organization, they are able to grow and develop, they are able to reproduce and pass on genetic information to their offspring, they are able to acquire and release energy, and they are able to maintain stable internal environments.
Explanation:
0 (zero) work done.
This is because work can be calculated by:
Work = Force × Distance
The force is 100 N and since the rock didn't move the distance is zero and so:
Work = 100 × 0 = 0 J
