Physics is a compulsory subject for students today. To learn physics well, we need to know the formulas, quantities, and symbols in physics. In this article we would like to explain to you what is a symbol in physics? along with many other Physics knowledge but you need to pay attention.

What is in physics? a What is the symbol in class 8, class 10 physics

In physics, many people confuse the symbols a and A. Usually a lot of people confuse these two quantities. In physics one is the unit quantity of acceleration m/s. and A is the unit measure of area m2.

Acceleration is a quantity that characterizes the transformation of the instantaneous velocity vector over time. Acceleration is a directional quantity also known as a vector quantity. The unit of standard acceleration is length divided by time squared i.e. m/s2 (meters/second squared).

Acceleration formula a:

In there:

  • a is the unit acceleration m/s2.
  • Δv is the instantaneous velocity vector variation.
  • v is the instantaneous velocity vector at time t.
  • v0 is the instantaneous velocity vector at time t0.
  • Δt is the time required to collect the change.

Illustrated exercise about a in physics

Question 1: An object moves in the positive direction of the Ox axis with the instantaneous velocity vector v constant

  1. The object’s instantaneous velocity vector is always (+).
  2. The coordinates always coincide with the distance.
  3. The object’s instantaneous velocity vector is always (+).
  4. The coordinates and instantaneous velocity vectors of the object always have the value (+).

Answer: C. The object’s instantaneous velocity vector is always (+).

Question 2: A car is traveling with v = 63 km/h, suddenly the driver sees a pothole in front of him, 82m away from the car. He slammed on the brakes and the car came to a pothole and stopped. Calculate acceleration and braking time.

Answer:

We have v0 = 63 / 3.6 = 17.5 m/s

Applying the formula v power 2 – v0 power 2 = 2.aS

a = v to 2−v0 to 2 = 2aS = -1.8673 (m/s2)

Where a = (v−v0)/t ⇒ t = (v−v0)/a = 9,371 (s)

Question 3: A car accelerates from 54km/h to 27m/s in that period, the car covers a distance of 80m. Calculate the acceleration time and acceleration of the car.

Answer:

s = 80m, vo = 54km/h = 15m/s, v = 27m/s

v2 – vo2 = 2as a = 3.15m/s2

v = vo + at t = 3.8s

Question 4: An electron moving with an instantaneous velocity vector of 5.105 m/s is accelerated to an instantaneous velocity vector of 5.4,105 m/s. Calculate the time and distance traveled by the electron while accelerating, given that the magnitude of the acceleration is 8,104 m/s2.

Answer:

vo = 5.105(m/s); a = 8,104m/s2; v = 5,4.105m/s

v – vo = at t = 0.5 s

v2 – vo2 = 2as s = 26,104 m

Question 5: A car A is traveling on a straight road with an instantaneous velocity of 40 km/h. Car B chases car A with an instantaneous speed of 60 km/h. Determine the instantaneous velocity vectors of car B with respect to car A and of car A with respect to car B.

Answer:

Choose the positive direction to be the direction of motion of the two cars

vAD: instantaneous velocity of car A relative to the ground.

vBD: instantaneous velocity of car B relative to the ground.

vAB: instantaneous velocity vector of car B relative to car A.

According to the instantaneous velocity vector addition formula, the instantaneous velocity vector of car A relative to car B is:

vAB = vAD + vDB or vAB = vAD – vBD

Since the two cars are moving in the same direction, vAB = 40 – 60 = -20(km/h) → opposite direction is positive.

⇒ vBA = 20(km/h) and vBA in the same positive direction.

Question 5: A car A is traveling on a straight road with an instantaneous velocity of 40 km/h. Car B chases car A with an instantaneous speed of 60 km/h. Determine the instantaneous velocity vectors of car B with respect to car A and of car A with respect to car B.

Answer:

Choose the positive direction to be the direction of motion of the two cars

vAD: instantaneous velocity of car A relative to the ground.

vBD: instantaneous velocity of car B relative to the ground.

vAB: instantaneous velocity vector of car B relative to car A.

According to the instantaneous velocity vector addition formula, the instantaneous velocity vector of car A relative to car B is:

vAB = vAD + vDB or vAB = vAD – vBD

Since the two cars are moving in the same direction, vAB = 40 – 60 = -20(km/h) → opposite direction is positive.

⇒ vBA = 20(km/h) and vBA in the same positive direction.
