Question

WILL GIVE MEDAL :D

In the absence of friction, gravity, and all other external forces, what kind of speed will an object display if it
travels from the bottom to the top of an inclined plane?

A) constant speed
B) increasing speed
C) decreasing speed
D) speed increases and then decreases
E) speed decreases and then increases

Answer 1

With no gravity and no friction, there is nothing slowing down the object.

Answer 2

@mathstudent55 so constant speed?

Answer 3

As there is no external force acting on the object,then what do you think about the speed ?

Answer 4

@rachelg1456

Answer 5

@mayankdevnani that it's increasing

Answer 6

Correct.
If no external forces act of an object in motion, it will continue at the same speed and direction forever.

Answer 7

how?

Answer 8

@mayankdevnani I think because (and im using the 'no external forces' thing), there is nothing making is slow down or speed up, therefore it stays the same

Answer 9

yeah! correct

Answer 10

As no external force is there,so no acceleration is there.Therefore,constant velocity is there(constant speed is there )
