Conceptual Question About Simple Motion

[jayadds]

If an object was thrown horizontally over a cliff, would you expect it to take longer ot hit the ground below than if it was just dropped over? Please explain.

Many thanks.

Many thanks.

What do you think? What affects the time taken to reach the bottom?

If we resolve a vector to a 90° component the result is zero. FCos90°=0
Thus orthogonal vector will not effect each other.

In your case the horizontal component(throwing horizontally) will not effect anything what the gravity doing to the object(pulling it down). Both orthogonal to each other.

If your horizontal velocity is very fast it is possible that the object will be in outer space even the dropping height is small.

This situation is very different depending on whether or not you want to take into account air drag. I suggest viewing this without drag.

If you dropped the object off the cliff, what force(s) would be affecting it during its flight?

Yes, I would expect the object to take longer to hit the ground if it was thrown horizontally over a cliff compared to if it was just dropped over. This is because when an object is thrown horizontally, it has an initial horizontal velocity in addition to the downward force of gravity. This horizontal velocity allows the object to travel further away from the cliff before being pulled down by gravity, resulting in a longer time before it reaches the ground. On the other hand, when an object is just dropped over a cliff, it only has the downward force of gravity acting on it, causing it to fall straight down and reach the ground faster. This can be explained by the principles of projectile motion, where an object's horizontal and vertical components of motion are independent of each other. Therefore, the object will take longer to hit the ground if it has a horizontal velocity component compared to when it is just dropped.
