use the exploration to explain the difference between observed motion, when force is applied in a direction which is same direct ion of motion and when it is against the direction of motion
1 answer:
Answer:
When a force acts on an object that is stationary or not moving, the force will cause the object to move, provided there are no other forces preventing that movement. If you throw a ball, you are pushing on it to start its movement. If you drop an object, the force of gravity causes it to move.Answer:

vcyl / vsph = 1.05
Explanation:
The kinetic energy of a rolling object can be expressed as the sum of a translational kinetic energy plus a rotational kinetic energy. The traslational part can be written as follows:
The rotational part can be expressed as follows:
where I = moment of Inertia regarding the axis of rotation. ω = angular speed of the rotating object. If the object has a radius R, and it rolls without slipping, there is a fixed relationship between the linear and angular speed, as follows:
For a solid cylinder, I = M*R²/2 (4) Replacing (3) and (4) in (2), we get:
Adding (5) and (1), we get the total kinetic energy for the solid cylinder, as follows:
Repeating the same steps for the spherical shell:
Since we know that both masses are equal each other, we can simplify (6) and (9), cancelling both masses out. And since we also know that both objects have the same kinetic energy, this means that (6) are (9) are equal each other. Rearranging, and taking square roots on both sides, we get:
This means that the solid cylinder is 5% faster than the spherical shell, which is due to the larger moment of inertia for the shell.
