What is Acceleration?​

Physics

Answer:

Depends on what are you looking at. All of the following are valid definitions, it just depends on which way you are analizing the problem.

<u>From a kinematics point of view:</u>

Acceleration is, by definition, is a vector quantity that measures the rate of change of the rate of change in position (add brackets if it helps visualizing the idea). This leads to the following different definitions - which are more like means of calculating it

  • the second derivative of position with respect to time a = \ddot x= \frac{d}{dt}({\frac d{dt}} x);
  • the first derivative of velocity with respect to time a = \dot v = \frac d{dt} v.

<u>From a dinamics point of view</u>

Acceleration is the effect of a force applied to a body, and measures the ratio of the force applied to a body of mass m and the mass itself (which is another formulation of Newton second law):

a = \frac Fm

Acceleration is the rate of change of velocity

 

To define acceleration, We need to know more about motion.

Motion: This can be defined as the change in position of a body from one point to another. When an object accelerates, it undergoes motion.

<u>Definition</u>

Acceleration can be defined as the rate of change of velocity. The S.I unit of acceleration is meter-per-squared seconds. (m/s²)

The formula of acceleration is

  • a = (v-u)/t................. Equation 1

⇒ Where:

  • a = acceleration
  • u = initial velocity
  • v = final velocity
  • t = time

Hence, Acceleration is the rate of change of velocity

Two runners start simultaneously from the same point on a circular 200-m track and run in the same direction. One runs at a cons
sladkih [1.3K]

Answer

given,

length of the track = 200 m

speed of runner 1 = 6.20 m/s

speed of the runner 2 = 5.5 m/s

distance covered by the fastest runner, d = 6.2 t

distance covered by the slow runner,d = 5.50 t + 200

time taken to overtake for the first time

 6.2 t = 5.50 t + 200

  0.7 t = 200

       t = 285.7 s

distance covered from the starting point

 d = 6.2 t

 d = 6.2 x 285.7

 d = 1771.43 m

for next overtaking time taken will be double

 t' = 258.7 x 2 = 571.4 s

distance travel by the runner from the starting point

d' = 6.2 t'

d' = 6.2 x 571.4

d' = 3542.68 m

Answer:

W=F×H,Power=W/Time

Explanation:

W=Force ×Height

750N×16 =12000

Power=Work/Time

12000/5=2400J

Which of the following is a characteristic of electromagnetic waves? (2 points)
muminat

Answer:

c They can only travel without a medium.

Explanation:

Electromagnetic waves are made up of electric field and magnetic field.

Here electric field will induce magnetic field and magnetic field will induce electric field.

So this type of field do not require any medium and in vacuum or air the speed of electromagnetic waves are same as speed of light

c = 3 \times 10^8 m/s

also we have different range of electromagnetic waves out of which a small range of electromagnetic waves is of visible region in which these waves are visible to us.

so correct answer is

c They can only travel without a medium.
