No
It is not exactly the same, but it is very similar. A space hopper has handles, and a regular rubber ball does not. A space hopper is also much larger than a normal rubber ball.
This is an example of inertia. The rolling ball has more mass, so it has greater inertia than the ping pong ball. This means it requires more force to stop the rolling ball compared to the ping pong ball at the same velocity.
scrawl rhymes with "ball" which is a round object used in games!
rubber ball
because cricket ball has greater mass
It is an example of momentum (sometimes called "inertia"). Velocity x mass. The bowling ball is much, much heavier. With both rolling at the same speed, the bowling ball is harder to stop because it has much more mass.
It is generally easier to stop a rubber ball moving at the same speed as a wooden ball of the same size, due to the rubber ball's elasticity and ability to deform upon impact, absorbing some of the energy. The wooden ball, being more rigid, would transfer more energy upon impact, making it more difficult to stop.
The rubber ball would bounce higher than the wooden ball when dropped at the same height. Rubber is an elastic material that can store and release more energy upon impact compared to wood, resulting in a higher bounce.
The simple answer to this is that the rubber ball is more 'elastic' than the tennis ball and, assuming they are both dropped from the same height onto the same surface, the tennis ball 'loses' more energy than the rubber ball when it strikes the surface the ball is bouncing off. Of course no energy is truly ever lost but rather it is transferred or converted into other forms, in this case the energy will be converted into thermal energy (as the balls deform upon striking the surface due to friction within the materials), sound (the noise you hear when the ball strikes the surface) and to varying extents energy is transferred to the surface which the balls are striking. This energy 'loss' is the reason why the balls do not return to the height the balls were dropped from originally and the amount of energy 'loss' will vary with the type of ball dropped.
No, the base is concidered in-play and still a live ball. It is the same thing as the ball bouncing off a fielder or a rock.
If they are both solid, and the incline is the same, the rate of acceleration will be the same.
Both balls experience the same acceleration due to gravity, which is approximately 9.81 m/s^2. Gravity acts downwards on both balls, causing them to accelerate towards the ground at the same rate regardless of their initial velocities.
