# Assuming No Friction: Calculating Speed at Point 2

In physics, friction is a powerful force that can affect the motion of an object. It can slow down or stop an object’s motion entirely. So what happens when we assume that there is no friction? In this article, we’ll look at how to calculate the speed of an object at Point 2, assuming there is no friction.

## How to Calculate Speed at Point 2

In order to calculate the speed of an object at Point 2, we must first determine the initial velocity at Point 1. This is done by taking the initial velocity of the object and subtracting the acceleration due to gravity. Once we have calculated the initial velocity, we can then use the equation v2=v1+at (where v1 is the initial velocity, a is the acceleration and t is the time taken to travel between Point 1 and Point 2).

Using this equation, we can calculate the final velocity at Point 2. This is done by taking the initial velocity, multiplying it by the time taken to travel between Point 1 and Point 2, and then adding the acceleration due to gravity. Once we have calculated the final velocity at Point 2, we can then calculate the speed of the object at Point 2 by dividing the final velocity by the time taken to travel between the two points.

## Factors to Consider

When calculating the speed of an object at Point 2, we must take into account the fact that friction is not present. This means that the acceleration due to gravity is the only force acting on the object. Also, the time taken to travel between Point 1 and Point 2 should be taken into consideration. If the time taken is too long, then the object may have slowed down due to air resistance.

Finally, we must also take into account any external forces that may be acting on the object. These could include wind resistance, the force of gravity, or any other forces that may be acting on the object.

## 

In conclusion, calculating the speed of an object at Point 2, assuming no friction, is relatively straightforward. By taking into account the initial velocity, the acceleration due to gravity, the time taken to travel between Point 1 and Point 2, and any external forces that may be acting on the object, we can accurately calculate the speed of the object.
