Question

the path of an object thrown into space under the gravity at certain angle is called​

Answer 1

Answer:

Work done by the force of gravity on the object is equal to the negative of the change of potential energy of the object.

W

g

=−ΔP.E

W

g

=−(mgh

−mgh

) OR W

g

=−mg(h

−h

1

)

But as the object lies on the same horizontal line of the ground i.e h

1

=h

2

=0

⟹W

g

=0

Thus work done by gravity force on the object is zero.

Answer 2

Answer:

Projectile motion is a form of motion where an object moves in parabolic path; the path that the object follows is called its trajectory. ... This depends on the initial velocity of the projectile and the angle of projection. ... there is one force applied at the beginning on the trajectory, after which the only interference is from gravity.
