Question

Two objects moving in the same speed and same start and end time?


A force was applied to two objects.
1st object can move forward x --------> a
2nd object can rotate freely.

Since the force applied is equally the same, lets say all factors resistance, and everything that can effect their movements... ARE THE SAME.

Will the two objects share the same speed?
And star and stop and the same exact time?

I believe they will have the same T and V.

Answer 1

wait.. when you consider rotation.. you need to tell about which axis it is rotating.. cause that matters..!! Rotation is not as simple as translation.. for translation.. we can simply consider the body is a point object.. but rotation .. you need to consider it as a rigid body.. cause for ex.. putting a force on a door at one end.. gives max acceleration.. and thus will have higher angular velocity.. but putting that same force near the hinge.. gives it zero acceleration.. and zero velocity!

Answer 2

and whats T and V? :P

Answer 3

And for rotation you talk in terms of angular velocity... and translation linear velocity.. even though they are similar.. they are quite different physical quantities! so you cannot compare them as such!

Answer 4

@Mashy

True, its hard to do so...
I just assumed that I could possibly know that the speed and start up time of the two objects is the same, since the force or torque applied is equal.

V=Velocity
T=Time

So I guess from your answer @Mashy it depends on the axis?
Its rotating at this axis:




Pretty much the casual axis I guess :P

Answer 5

So @Mashy what do you think?
