Question

The upward velocity at any point during the flight of an object is ______the downward velocity at that point.

Answer 1

Answer:

When you project the object upward, the initial velocity when you release it is negative or less than zero (vi < 0).

Answer 2

The upward velocity at any point during the flight of an object is equal to the downward velocity at that point.

Explanation:

• The object slows down until it reaches a maximum height, at which point the velocity is zero.
• Then when the object falls towards the ground the velocity increases.

• If an object is dropped from a higher height only (as opposed to thrown), the initial velocity of the object is 0 m/s.

• If an object is projected upwards in a perfectly perpendicular direction, it will slow down as it moves upwards.

• Assuming that the object is not accelerating on its own, the force of gravity acts to slow it down. It follows the path of a parabola.
• Acceleration and velocities have opposite directions and in the end the always existing acceleration "eats up" the upward direction of velocity.
• A stone thrown in the sky falls back to the earth because there is a force that pulls it down towards the earth.
• According to Newton's first law of motion, "An object either remains at rest or moves with a constant velocity unless an external force is applied to it".
