How does the velocity of a moving object depend on the choice of frame of reference?
Imagine you threw and caught a ball while you were on a train moving at a constant velocity past a station. To you, the ball appears to simply travel vertically up and then down under the influence of gravity. However, to an observer stood on the station platform the ball would appear to travel in a parabola, with a constant horizontal component of velocity equal to the velocity of the train. This is illustrated in Figure 1 below.
(Path of the ball as seen by an observer on the train and an observer at the station.)
The different observations occur because the two observers are in different frames of reference. A frame of reference is a set of coordinates that can be used to determine positions and velocities of objects in that frame; different frames of reference move relative to one another.
The laws of physics are the same in all inertial frames (this is known as Galilean invariance). Put in another way, there is no experiment that you could do to determine which reference frame you are in (Einstein used this hypothesis to devise the theory of Special Relativity). This means that we can address problems in any reference frame to give an equivalent solution.

Yes or no?
Answer:
Yes :) rjhehrhrhridjrieuuririeirurhryyrur
Answer:
no
Explanation:
What's the difference between radioactivity and radiation? As we have seen, radioactive decay is a property of a particular nucleus. In comparison, radiation is a possible consequence of many processes, not just radioactivity. ... non-ionising radiation: essentially the low-energy parts of the electromagnetic spectrum.

What physical property could you use to identify the mineral, no matter how big a piece you found?  A) color B) density C) mass D) shape
Answer:
A and B
Explanation:
You can identify a mineral by its appearance and other properties. The color and luster describe the appearance of a mineral, and streak describes the color of the powdered mineral. Each mineral has a characteristic density. Mohs Hardness Scale is used to compare the hardness of minerals.
The unicorn suddenly ran through the school at 5.6 m/s and it has a mass of 450 kg. What is the unicorn’s kinetic energy?
Answer:
KE = 567000 J
planation:
The kinetic energy of the unicorn can be find out from its mass and velocity. The kinetic energy of unicorn is 7056 J.
What is kinetic energy ?Kinetic energy is a form of energy on an object generated by virtue of its motion. It is related to the mass and velocity of the object by the expression written below:
Ke = 1/2 m v²
When an object starts moving from rest, its potential energy converts to kinetic energy. As the mass and velocity increases, kinetic energy increases.
Given that, m = 450 kg
v = 5.6 m/s
then , Ke = 1/2 450 kg × (5.6 m/s )² = 7056 J.
Therefore, the kinetic energy of the unicorn is 7056 J.

Actually, Sherman, there are more black moths than white ones because...
Answer:
Actually, Sherman, there are more black moths than white ones because of natural selection. The black moths blend into the environment, while the white moths do not. This means that the predators of the moths will find and eat more white moths than black moths. Then, this leads to more black moths and fewer white moths, since black moths have a better chance of surviving and reproducing.

A skateboarder pushes the ground with one foot, and moves forward.
Which statement BEST explains his motion?
The mass of the skateboard decreased causing acceleration to move him forward.
The unbalanced force exerted by the skateboarder’s foot caused him to move forward.
The mass of the student and skateboard increased causing acceleration to move him forward.
The balanced forces on the skateboard allowed it to change his motion and move him forward.
Answer:
C or D i would think would be the answer
The unbalanced force exerted by the skateboarder’s foot caused him to move forward.
When a skateboarder pushes the ground with one foot, the board moves forward. This is because of the unbalanced force exerted by the skateboarder’s foot caused him to move forward.
This is an application of Newton's first law, which states that, an object in motion or uniform motion will continue its state unless it is acted upon by an external unbalanced force.
Here, the unbalanced force exerted by the foot on the ground causes the board which was at rest to move forward.
