# Can an object move without force?

## Can an object move without force?

Acceleration is the change of velocity per unit time, so if there is no force, all we know is that the acceleration is zero. Therefore, the velocity is not changing. If the object was already moving, then it will just keep moving. So, yes, the object can be moving when there is no force applied to it.

What is the mass of an object if a force of 17 and causes it to accelerate at 1.5 m/s s?

What is the mass of an object that requires a force of 15 N to accelerate it at 1.3 m/s s?

Answer. your’s answer is here. so , mass of that Object is 6 Kg.

### Which law governs when two skaters push apart in a rink?

Newton’s Third Law of equal and opposite forces is very important when considering collisions between objects or propulsion. In these situations, all of the forces are internal, which means that for every force, there will be an equally sized force in the opposite direction. An example is two skaters out on the ice.

Why doesn’t the Earth appear to move when you push down on it with your foot?

Earth has so much mass compared to you that it does not move noticeably when you push it. If you step on something that has less mass than you do, like a skateboard, you can see it being pushed back.

Do we pull the earth upwards?

Does Earth accelerate towards you when you jump from a height? You may find it hard to believe but the answer is yes. You don’t see the acceleration since it is very small, but you do move the Earth just as the Earth moves you due to gravity.

#### Why do we not feel the earth moving?

We can’t feel Earth rotating because we’re all moving with it, at the same constant speed. Image via NASA.gov. It’s because you and everything else “ including Earth’s oceans and atmosphere “ are spinning along with the Earth at the same constant speed. It’s only if Earth stopped spinning, suddenly, that we’d feel it.

How much does the earth move when you jump?

To cut to the chase, Allain found that our jump would push on the Earth ever so slightly, giving it a recoil speed of 2.6 x 10^-13 m/s. That is, in one second, Earth would move about a hundredth of the radius of a single hydrogen atom .

What would happen if everyone on Earth jumped at the same time at the same place?

The ground would begin to shake, and if the jump happened near the coast, it could trigger a tsunami with 100-feet-tall waves. The shaking could also lead to an earthquake falling in the 4-8 magnitude range.

## What would happen if everyone flushed the toilet at the same time?

If everyone in the United States flushed the toilet at the same time, sewer systems across the country would be overwhelmed with wastewater. The average home in America is outfitted with sewer pipes around four inches in diameter.

What would happen if everyone in China jumped at the same time?

The result – if everyone on the planet congregated at one point, and simultaneously jumped, the net impulse to the earth would jiggle it about 1/100 the radius of a hydrogen atom over a second.

What would happen if everyone on Earth disappeared?

Lacking human oversight, glitches in oil refineries and nuclear plants could lead to fires, nuclear explosions and fallout. Earth would flourish. It appears the vast over population and pollution of the world is the result of over thirty millennia of struggle to reach the Moon…
