Is gravity velocity-dependent?

The fact that the speed of gravity is finite is what induces this gravitational aberration, but the fact that General Relativity (unlike Newtonian gravity) has velocity-dependent interactions is what allowed Newtonian gravity to be such a good approximation.

Which forces are velocity-dependent?

(at which the gravitational and air resistance forces balance).

What is dependent on the velocity of an object?

Direction of the Acceleration Vector. Note in the diagram above that there is a velocity change for an object moving in a circle with a constant speed. The acceleration of the object is dependent upon this velocity change and is in the same direction as this velocity change.

Is friction a velocity-dependent force?

Friction does depend on the sliding velocity, but this de- pendence is far from universal: some measurements find an increase when velocity increases, while others find a decay [8–10] or even a more complex non-monotonous behavior [2].

How fast would an egg fall?

Gravity is the force that attracts mass towards the center of the earth or other large planetary body. The speed of gravity is about 9.8 meters per second. An unprotected egg would fall at about 10.93 meters per second.

Is velocity dependent on acceleration?

When the velocity of an object changes it is said to be accelerating. Acceleration is the rate of change of velocity with time. That’s because acceleration depends on the change in velocity and velocity is a vector quantity — one with both magnitude and direction.

Are velocity dependent forces Conservative?

describes motion under a conservative force, but this is not the most general possible Hamiltonian.

Is mass dependent or independent?

Independent Variable is the volume of the object. Dependent Variable is the mass of the object.

Is work dependent on velocity?

So to reiterate again, velocity has no direct bearing on the applied work. It will affect the required power, but the amount of work required to move the specified distance only depends on the displacement and the applied force; not upon how quickly it travels the displacement.

Is kinetic friction independent of velocity?

3. The kinetic friction force is independent of the sliding velocity, V.

Is kinetic friction dependent on velocity of the body?

Frictional force is independent of the velocity of the body.

What is velocity dependent force?

Velocity Dependent Forces Consider a particle of mass moving in one dimension under the action of a force, , which is a function of the particle’s speed, , but not of its displacement, . Note that such a force is intrinsically non-conservative [since it clearly cannot be expressed as minus the gradient of some potential function, ].

Is magnetic force dependent on velocity?

The magnetic force is also a velocity-dependent force — apparently depending on the absolute velocity. However, one can treat any inertial frame as stationary, and the force will be proportional to the velocity of the particle in that frame.

How does air resistance affect the downward velocity of an object?

It follows that air resistance prevents the downward velocity of our object from increasing indefinitely as it falls. Instead, at large times, the velocity asymptotically approaches the so-called terminal velocity, (at which the gravitational and air resistance forces balance).

What are some examples of forces in everyday life?

Another interesting force in everyday life is the force of drag on an object when it is moving in a fluid (either a gas or a liquid). You feel the drag force when you move your hand through water. You might also feel it if you move your hand during a strong wind. The faster you move your hand, the harder it is to move.
