Acceleration is one factor in the Twin Paradox, which investigates why a moving reference frame experiences time at a different rate from a stationary frame (and why this effect only works in one direction). The effect of special relativity "slows down" time on an object accelerated and maintained at increased velocity with respect to its original location. However, general relativity also affects time passage and will "speed up" time on an object accelerated to a different gravitational potential (for example, an orbiting satellite). Experiments with atomic clocks in 1972 and 1997 established that clocks moving at increased altitude (in any direction) will run faster because of their increased distance from the Earth's gravitational center. Clocks travelling westward also run faster because they are moving more slowly than the Earth spins. Clocks travelling eastward were moving faster than the Earth's spin and this caused them to run more slowly, as predicted by special relativity. Clocks at the poles will also run faster than clocks at the equator for the same reason, but the difference is measured in billionths of a second.

Acceleration is caused by any forces?

Roughly speaking, acceleration is caused by destroying the balance of forces on an object.


Acceleration is caused by?

Acceleration is caused by a change in an object's velocity, either in speed or direction. This can occur due to the application of a force to the object, such as gravity or a push or pull from another object.


Are inertial and gravitational acceleration equal?

No, inertial and gravitational acceleration are not equal. Inertial acceleration is caused by changes in velocity due to forces acting on an object, while gravitational acceleration is caused by the force of gravity on an object due to its mass.


Is acceleration caused by two forces which are opposite to each other?

No, acceleration is caused by an imbalance of forces acting on an object. If the two forces are equal in magnitude and opposite in direction, they will cancel out and there will be no acceleration. Acceleration occurs when there is a net force acting on an object.


What is the acceleration of a falling object caused by?

Newton's Second Law of Acceleration says it is gravity.


What is the caused when forces are not opposite and equal?

acceleration


What is acceleration caused by?

Acceleration is caused by a change in an object's velocity over time. This change can result from forces such as gravity, friction, or applied forces. The direction of the force will determine the direction of the acceleration.


The acceleration of a falling object is caused by th force of?

Gravity


Is the acceleration cause by the gravity constant?

acceleration caused by gravity is not the same because it varies from the mass and the distance betwwen the two objects


What causes a change in acceleration and velocity?

Acceleration is the change in velocity and/or What_three_ways_can_acceleration_change_an_objects_motionof an object. Acceleration can either speed an object up, slow it down (deceleration), or change the direction in which the object is moving.


What is the acceleration caused by your push on a ball?

The acceleration of the ball would depend on its mass and the force of the push. This is because force = mass times acceleration. You could manipulate this equation to solve for acceleration by dividing each side by mass. Acceleration therefore equals force/mass.


What is acceleration toward the center of a circle caused by?

The force which causes acceleration towards the centre of a circle is called Centripetal force but what causes it can vary.
