# Circle Deflection: Calc Outbound Angle After Collision

• cam875
In summary, circle deflection is the change in direction of a circular object after a collision. Calculating the outbound angle after collision is important for predicting the object's trajectory and understanding the system's dynamics. Factors such as angle of incidence, mass, velocity, and elasticity affect the outbound angle. It can be calculated using the law of reflection and can be altered by changing these factors or external forces.

how do u calculate what one circle does when it collides with another circle at a specific point on a specific heading? I need to know how to figure out the outbound angle that the circle will travel on after colliding.

Isn't this just the reflection law, $$\theta_{inbound}=\theta_{outbound}$$ with theta measured on the tangent (plane) of the collision surface at the collision point?

im not sure that's why I am asking.

## What is circle deflection?

Circle deflection is a term used in physics to describe the change in direction of a circular object, such as a ball, after a collision with another object or surface.

## Why is calculating the outbound angle after collision important?

Calculating the outbound angle after collision is important because it allows us to predict the trajectory of the circular object after the collision, which can help us understand the dynamics of the system and make accurate predictions.

## What factors affect the outbound angle after collision?

The outbound angle after collision is affected by several factors, including the angle of incidence, the mass and velocity of the circular object, and the elasticity of the objects involved in the collision.

## How is the outbound angle after collision calculated?

The outbound angle after collision can be calculated using the law of reflection, which states that the angle of incidence is equal to the angle of reflection. This can be done by using trigonometric functions and taking into account the factors that affect the angle.

## Can the outbound angle after collision be altered?

Yes, the outbound angle after collision can be altered by changing the factors that affect it, such as the angle of incidence, the mass and velocity of the circular object, and the elasticity of the objects involved in the collision. Additionally, external forces such as friction and air resistance can also alter the outbound angle after collision.
