My objects are falling to slowly when a rigidbody is attached, cab you help?

There are a lot of misconceptions here. Do not do the following:

• Change the force of gravity in your scene.

• Add an extra force in code.

• Change the mass.

~A very long time ago, Galileo found out mass doesn't affect freefall time. I am very confident the problem with your scene is the scaling. Look at this gif: These objects are all the same except in that they are larger than each other. Keep in mind that, in Unity, 1 unit = 1 meter. Scale everything accordingly. If everything is scaled properly, I promise everything will fall realistically. If you have an object with a very large size, it will fall extremely slowly.

i think its a coding mistake , you're setting the rididbody.velocity.y = 0 in the code somewhere, and that makes the jumping fast (since its a force set from code) but the falling slow since its not set from code , the physics update get a few milliseconds between each Update frame to do its physics thingy but it get stopped once the velocity.y = 0 happens , or atleast thats the problem i had ...

Are you sure that no other script are running elsewhere and impacting your falling speed ?

Are you sure you didn't alterate the time flow (Project settings/Time) ?

Maybe you have modified the weight of your object or the gravity of the app ?

I'm having the same problem. I've narrowed it down to the Animator - when I disable the Animator component, the object falls as expected... not sure why

I had an issue like this, I was doing some first person rigidbody-based movement, and this was my code

     void Update()
     {
         float hMove = Input.GetAxisRaw("Horizontal");
         float vMove = Input.GetAxisRaw("Vertical");
 
         MoveDir = (hMove * transform.right + vMove * transform.forward).normalized;
     }
 
     void FixedUpdate()
     {
         Move();
     }
 
     void Move()
     {
         rb.velocity = MoveDir * speed * Time.deltaTime;
     }

and it was working all well and fine, until I started to the jumping portion of the script, the player fell like a feather. I hadn't changed any gravity or mass or anything like that, but what was causing the problem is that when I set rb.velocity to MoveDir, MoveDir.y = 0, so every fixed update the object was barely falling. So to fix this issue I did this

void Update() { float hMove = Input.GetAxisRaw("Horizontal"); float vMove = Input.GetAxisRaw("Vertical");

         MoveDir = (hMove * transform.right + vMove * transform.forward + new Vector3(0, rb.velocity.y, 0)).normalized;
 // i gave MoveDir a y value of whatever the y velocity was at the time, so it was essentially unaffected.
     }
 
     void FixedUpdate()
     {
         Move();
     }
 
     void Move()
     {
         rb.velocity = MoveDir * speed * Time.deltaTime;
     }

Hope this helps!
