    Velocity
In summary, the question is about two objects being thrown horizontally at the same time with different velocities. The conversation concludes that both objects will reach 0m/s at the same rate due to the constant acceleration of gravity, but one will start closer to 0m/s. Therefore, the object that starts moving towards the ground first will hit the ground first. The individual asking for clarification believes that the object with a higher velocity will hit the ground first.

Velocity Question Please help!

When two objects are thrown horizontally at the same time? one has velocity 12m/s and other has velocity of 16 m/s // which object would fall first?

Well, the object is always experiencing one acceleration in this case: gravity, and we all know that is 9.81 m/s^2 down. So which of the balls will reach 0 m/s first, if one starts at 12 and the other 16? Neither one has an advantage in the rate at which they go to 0 m/s... They both move towards 0m/s at the same rate. One is just closer to being at 0m/s to start. So ... Draw your conclusion.

BTW, I say 0m/s because they are both accelerating down all the time. Once they reach 0m/s, they will be falling at the very next instant in time, so whichever reaches 0m/s first is the one that will be falling first.

And very obviously, whichever one starts moving towards the ground first is going to be the one that HITS the ground first. I hope that part is at least clear and assumed.

can you please eloborate on this... i think the one with higher speed hits the gorund first based on the information but please reply back
 

1. What is velocity?

Velocity is a measure of an object's speed and direction of motion. It is a vector quantity, meaning it has both magnitude (speed) and direction.

2. How is velocity different from speed?

Speed is a measure of how fast an object is moving, while velocity also takes into account the direction of the object's motion. For example, a car traveling at 60 miles per hour east has a different velocity than a car traveling at 60 miles per hour west.

3. How is velocity calculated?

Velocity is calculated by dividing the distance traveled by the time it took to travel that distance. The formula for velocity is v = d/t, where v is velocity, d is distance, and t is time.

4. What are some common units for velocity?

Velocity can be measured in a variety of units, depending on the system of measurement being used. Some common units for velocity include meters per second (m/s), kilometers per hour (km/h), feet per second (ft/s), and miles per hour (mph).

5. Can velocity be negative?

Yes, velocity can be negative if the object is moving in the opposite direction of the chosen reference point. For example, if a car is traveling east and its velocity is measured with a reference point facing west, the velocity would be negative.
