Rock wont roll uphill

Hey, I have a rock that the player can roll around. The problem is that when the player tries to roll it up a hill or ramp, it just wont do it.

Here’s the script:

local boulder = script.Parent
local pushForce = 500
local friction = 0.3
local maxForce = 8000

boulder.Touched:Connect(function(hit)
    local character = hit.Parent
    local player = game.Players:GetPlayerFromCharacter(character)

    if player then
        local bodyForce = Instance.new("BodyVelocity")
        bodyForce.MaxForce = Vector3.new(maxForce, maxForce, maxForce)
        bodyForce.Velocity = character.PrimaryPart.CFrame.LookVector * pushForce
        bodyForce.Parent = boulder

        wait(0.5)
        bodyForce:Destroy()
    end
end)

game:GetService("RunService").Stepped:Connect(function(_, deltaTime)
    local velocity = boulder.Velocity
    if velocity.Magnitude > 0 then
        local deceleration = velocity * -friction * deltaTime
        boulder.Velocity = velocity + deceleration
    end
end)

Here’s a video of the problem (idk why its so low quality):

If anyone knows how to fix this, please send ur ideas.

The Ramp or ball is probably too large for the ball to roll but here is the script:

local boulder = script.Parent
local pushForce = 500
local friction = 0.3
local maxForce = 8000
local db = false

local runService = game:GetService("RunService")
local players = game:GetService("Players")

runService.Heartbeat:Connect(function(deltaTime)
	if boulder.Velocity.Magnitude > 0 then
		local deceleration = boulder.Velocity * -friction * deltaTime
		boulder.Velocity = boulder.Velocity + deceleration
	end
end)

while runService.Heartbeat:Wait() do
	local touchingParts = workspace:GetPartsInPart(boulder)
	for _, part in ipairs(touchingParts) do
		local character = part.Parent
		local player = players:GetPlayerFromCharacter(character)

		if player and not db and character:FindFirstChild("Humanoid") and character.PrimaryPart then
			db = true
			local bodyVelocity = Instance.new("BodyVelocity")
			bodyVelocity.MaxForce = Vector3.new(maxForce, maxForce, maxForce)
			bodyVelocity.Velocity = character.PrimaryPart.CFrame.LookVector * pushForce
			bodyVelocity.Parent = boulder

			task.wait(0.5)
			db = false
			bodyVelocity:Destroy()
		end
	end
end

You need to add a gradual smoothing to the ramp, it is too steep to roll the ball up even with these modifications
