The first thing you should know is that acceleration is a vector, therefore, it has magnitude, and direction.
By definition, we have that the vector acceleration is given by:
Where,
dv/dt: derived from the velocity vector with respect to time,
Therefore, the units of the vector acceleration are:
The symbol of acceleration is:
Answer:
The statements about acceleration that are true are:
a. the si units of acceleration are m/s2.
b. for acceleration, you must have a number, a unit, and a direction.
d. the symbol for acceleration is (True, only if the symbol is the same as above)
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)
