Question Calculate Initial/Launch Velocity

Hi All,

I have one doubt in physics part in unity. Is it possible to calculate initial velocity of the object before it launches by using height, acceleration, displacement ?

User giving the force and angle manually by dragging and goes up and down. The ball/bomb doesn't launch from Cannon. Once Player release the mouse it instantiate the bomb and get the velocity by using rigidbody.velocity. Is it possible to calculate before it instantiate the bomb? I hope there must be the some physics bowl hidden in unity to calculate before it launches.

If you can help me on that, it would be really helpful for me




Please feel to ask any questions/ need detailed explanation on this part.

I dont get your question to be honest. What is the goal?

 

I need to calculate my velocity before bomb launches.

 

to do what? Do you want to predict the path it will go, or generate the force so that the ball has a certain velocity?

The former can be just written as myRigidBody.AddForce(yourVelocity, ForceMode.VelocityChange);

 

I want to predict my bomb velocity before it launches

 

Velocity = acceleration * deltaTime + OldVelocity. Acceleration = force/mass

 

Okay, let me try this .. What meant by old velocity?

 

zero vector

 

@ajitrko7 Calculating launch velocity is pretty easy once you learn about "projectile in motion".
If you haven't solved it all already,
Here is a small step-by-step guide that explains how to do it, I hope you find this helpful.
