4. Description of the action 4 The ball is falling down on the inclined plane and it fall down to the bucket. Then the m0(1) mass of the ball causes the pulley to act and the load increases, and the load activates the mechanism and creates a force on the m0(2) ball.

5. 5 In Parameter Ball m0(1) mass is 0.5 Kg. Out Parameter Ball m0(2) acceleration 3 ms-2.

6. 6 Physics Concepts Applied Gravitational acceleration : 9.81ms-2 The tension of tread is equal in everywhere. Ignore Air resistance. Inclined surfaces are frictionless. Pully is frictionless.

7. 7 Components and Materials Pully. For transfer the force to M0(2) ball . Inclined plane. For rolling ball. Balls. For transfer the forces. Container. For working of pully. String . For Wood block and container combined. Step-by-Step Process The ball m0 (1) go down on first Incline plane and fall down to the container. Container go down, pully and wood block go up. The wood block hit the second plane and it rotate to right side. Due to the action of that mechanism, a force is generated on the ball and the ball moves forward.

8. 8 Challenges faced The ball m0(1) may arrive at speed and slip away from m2 . Calculating the tension in the rope connecting the weights . Understanding how the weights m₁, m₂, and m₀ interact and affect each other. Solution Implemented The problem can be minimized by maintaining the right angle . Balancing forces on the inclined plane and in the pulley system to find the equilibrium conditions.

9. 9 Testing Process Make a small prototype and tested how it works. Iterations made Found out The first plane angle circle as a challange .

10. 10 The system begin with this step and Finally the ball 2 is rolling on the second plane with 3 ms-2 and it goes to the Step 04.
