How would playing a game of soccer, baseball, or basketball be different if inertia didn’t exist?
Elina [12.6K]
This would be a funny game.

Inertia, according to first Law of Newton, means that when you throw a ball it will continue moving unless a force acts over it.

Without inertia, the ball instead of continue moving, would stop as soon as it leaves your hand or foot. You had to stay pasted to the ball unitl it reaches the desired destiny for it continue moving.

A simple machine has efficiency 90%. What does it mean? No machine has 109 efficiency,why?​
Marrrta [24]

Answer:

<em>Efficiency of a machine is 90% this means that the total energy produced to the machine only 90% is useful and given as a output.</em>

<em>Machines are not 100% efficient because some of the work done by a machine is used to overcome friction</em>

Why might a wine glass survive a fall onto a carpeted floor but not onto a concrete floor? 1. since the carpet is softer than th
user100 [1]
Answer:
1. Since the carpet is softer than the concrete and the force of impact is reduced by the extended time of impact.

Explanation.
The carpet provides energy dissipation over a porous layer of material.
Because of this, the carpet behaves as if it was a spring and a dashpot.

The spring absorbs the kinetic energy, and the dashpot dissipates the energy.
The ticker the carpet, the better the energy dissipation will be.
