Physics

Asked by Byron

The bumper cars crash into each other and stop, explain why both bumper cars stop after the crash

Usually, the cars would move because the kinetic energy they had before the crash would have been conserved. In this case, the kinetic energy is not conserved so, they stop moving. The kinetic energy may have been converted into thermal energy.

Asked by Himadritanaya

Why physics and technology depended on each other

Hello again. I meant to say that the flip side of the argument, as advancements in computing, measurement and materials science are made, our ability to isolate and design experiments to examine the physical universe expand. So technology depends on physics. Physics depends on technology. Ian

Asked by Neo

It is likely that you can hit someone in the stomach, for example at a speed of 15 m / s ? (the person performing the blow is normally strong)

If you Google average speeds of vehicle you will notice that the typical speed for a car is 13 - 30 m/s. So, unless you can punch someone as fast as a car, I doubt it

Asked by Pema

What is the relationship between physic, technology and nature

Physics is a description of the fundamental laws which govern how matter, forces and waves interact. Our understanding of Physics is incomplete and improving over time, but the laws themselves are fixed. Nature consists of all the naturally occurring (i.e. not man-made) objects in the universe, e.g. planets, stars, rocks, trees, animals etc. Technology is invented by humans and used to build artif... more

Relationship between physics and the impact of industries

It depends on the industry, but physics is the backbone of subjects like mechanics, electronics, etc. The deeper the knowledge of a company has of physics on its products or production process the more competitive advantages it might have.

Asked by Subhash

What is the difference between physics and Technology

Physics is the knowledge of the world around you. The forces, materials, energy and how they interaction. Technology is an ability to 'take knowledge'... Take the physics knowledge and do something constructive with it in the real world. Knowledge is useless until it is applied.

Asked by Daria

When the toy car rolls down the sclope ,some energy is transfered to the surrounding as the thermal energy how should i calculate the amount of energy transferred to the surrounding

One way to do it is using the work equation. Where: Change in thermal energy = heat added to the system - work done by the system. In this case, if you calculate the work done by a car rolling down a slope you can obtain the energy transferred to the surrounding as the heat added to the system

Physics

Asked by Jean

What is the main phsse of a star?

After the elements in the star start to fuse it gets hot and it blows away surrounding material, then starts the main sequence stage, the stars inward force of gravity and outwards force due to fusion are in equilibrium, at the same time hydrogen nuclei fuse to form helium. Depending on the mass of the star will determine if it will turn into a red giant or super red giant which happens when the h... more
