Yes. That's the main reason that it's still here, following Earth
around the sun, and has not drifted off into space.
9.8 meters per second squared on or near the Earth acceleration due to gravity is not affected by the presence or absence of air
First of all, the atmosphere is the air. Secondly, air is matter, all matter is affected by gravity. Imagine this: the sea is liquid, it lies on the earth, pulled by gravity. the atmosphere is also like this except it is a "sea" of air, it lies on the earth, pulled by gravity.
No, only weight is affected by gravity: attraction, force, acceleration.
No. Weight is affected by gravity.
The measurement of weight is affected by gravity.
Electricity is not directly affected by gravity. Gravity does not impact the flow of electricity through wires or circuits.
Weight is affected by gravity, while mass is not. Weight is the force exerted by gravity on an object, and it depends on the mass of the object and the strength of the gravity acting on it. Mass, on the other hand, is a measure of the amount of matter in an object and remains the same regardless of the gravitational field it is in.
Rockets are affected by thrust (produced by engines), drag (air resistance), gravity (pulling the rocket down), and mass (the rocket's weight and payload). These factors impact the rocket's ability to overcome gravity and travel through the atmosphere.
The weight of an object is the measurement that is affected by gravity. Gravity is what gives objects weight, causing them to be pulled downwards towards the Earth.
Air planes are affected by gravity too, just like everything else. What makes them fly is that the upward force of the wings is bigger than the downward force of gravity.
Density is not affected by gravity. Density is affected by mass and volume, such that density = mass/volume. Weight, but not mass, is affected by gravity. Weight and mass are not the same thing.
Yes, there is an object affected by only gravity. Stars and other floating space debris are only affected by gravity in space, as long as the objects do not touch each other.
