Force is defined as mass times acceleration. In relativistic physics, we see that mass can change, for example, as an object approaches the speed of light it becomes more massive. When you apply force to such an object, you will still get some amount of acceleration, but possibly a very small amount, and you may also get an increase in mass. If the object had been moving at a slower speed you might have observed a greater acceleration and no increase (or no detectable increase) in mass. But in either case, the product of mass times acceleration remains the same.

What is motion always relative to?
Motion is always relative to the observers frame of reference. For example, if two people were standing facing each other, and a dog walked between them, one person would observe the dog's motion as going to the right, and the other person would observe the dog's motion as going to the left.
What are the two postulates from which Einstein developed the theory of relativity?
Einstein's two Relativity postulates are : 1. The Principle of Relativity or all motion is relative. Einstein discussed this in the example of a magnet and a conductor in motion relative to each other; 2 the second postulate is that light is always propagated in empty space with a definite velocity c which is independent of the state of motion of the emitting body.
Which of the following must always be measured or described relative to something else?
Quantities such as speed, temperature, and position must always be measured or described relative to a reference point or standard in order to have meaning. For example, speed is measured relative to a specific point in time, temperature is measured relative to a chosen scale, and position is described relative to a coordinate system.
Why do observers on Earth only ever see the same side of the moon?
Observers on Earth only ever see the same side of the moon because the moon's rotation period is the same as its orbital period around Earth, causing one side to always face towards us.
Is distance always relative?
Distance is a measurement of the space between two points, which can be objective and not always relative. However, in certain contexts, distance can be subjective or appear to vary depending on the observer's frame of reference.
What one measurement will two observers in relative motion always agree upon?
time
What is motion always relative to?
Motion is always relative to the observers frame of reference. For example, if two people were standing facing each other, and a dog walked between them, one person would observe the dog's motion as going to the right, and the other person would observe the dog's motion as going to the left.
Can corresponding angles have the same measurements?
Yes they always do have the same degree of measurements
How do you explain why a square is always symmetric?
explain why a square i always symetric
When did measurements start?
Measurements are probably as old as mankind.People have always needed to measure something.
What are the two postulates from which Einstein developed the theory of relativity?

Einstein discussed this in the example of a magnet and a conductor in motion relative to each other; 2 the second postulate is that light is always propagated in empty space with a definite velocity c which is independent of the state of motion of the emitting body.
Do you always need to find all the measurements in a triangle when you are trying to classify it?
no
When a star travels from a position below the observers horizon to a position above the observers horizon the star is rising?
The star is considered rising. Also, it is setting when it is the opposite (moving from above the horizon to below.)
Which of the following must always be measured or described relative to something else?
Quantities such as speed, temperature, and position must always be measured or described relative to a reference point or standard in order to have meaning. For example, speed is measured relative to a specific point in time, temperature is measured relative to a chosen scale, and position is described relative to a coordinate system.
Why is relative frequencies important?
It depends on the circumstances. It is not always important
Why do observers on Earth only ever see the same side of the moon?
Observers on Earth only ever see the same side of the moon because the moon's rotation period is the same as its orbital period around Earth, causing one side to always face towards us.
What is a complete relative clause?
A relative clause always begins with a relative pronoun that is substituted for a noun, a noun phrase, or a pronoun when sentences are combined. A relative clause functions like an adjective, giving more information on a noun.
