Explain velocity and gradient

Tanya [424]

Velocity is a measure of how fast something moves in a particular direction. In other words, a velocity is a speed with a direction. For instance, if an object moves east at 9 metres per second (9m/s), we would say that its velocity is 9 m/s to the east.

Gradient The formal definition of a concentration gradient is the process of particles, which are sometimes called solutes, moving through a solution or gas from an area with a higher number of particles to an area with a lower number of particles. The areas are typically separated by a membrane.

Two ice skaters stand facing each other. The first skater has a mass of 100 kg and the second has a mass of 50 kg. They push eac

olga_2 [115]

The second skater accelerates at 6 $m/s^2$ to the right.

Let the first skater be F.

Let the second skater be S.

Given the following data:

Mass of F = 100 kg

Mass of S = 50 kg

Acceleration of F = 3 $m/s^2$

To find the acceleration of the second ice skater, we would apply Newton's Second Law of Motion:

Mathematically, Newton's Second Law of Motion is given by this formula;

$Force = Mass$ × $acceleration$

Substituting the given values, we have;

$Force = 100$ × $3$

Force = 300 Newton

Note: The same force is acting on the two ice skaters and the second ice skater would be pushed in the opposite direction (right).

Now, we would find the acceleration of the second ice skater:

$Acceleration = \frac{300}{50}$

Acceleration of S = 6  $m/s^2$ 

Therefore, the acceleration of the second ice skater is 6 $m/s^2$ to the right.
