Question

What is that said to be when an object can overcome the downward gravitational pull of the earth.
options are
1) Initial velocity
2) Final velocity
3) Recoil velocity
4) Escape velocity​

Answer 1

I think the answer is 4) Escape velocity

Answer 2

Escape velocity is the velocity when an object can overcome the downward gravitational pull of the earth.

•Escape velocity is that the minimum velocity that a body must attain to escape the field of force of the earth.

•Initial velocity is the velocity which the body has in the beginning of the given time period.

• Final velocity is the velocity which the body has at the tip of the given period of time .

•Recoil velocity is the velocity which is the kickback or a backward movement that a shooter feels when the bullet is discharged.

It can also be said as a backward velocity.

So, Escape velocity is velocity which is used to escape the gravitational force. (option 4)
