Hello guys, I hope you all are doing great. In today’s tutorial, we will have a look at Difference Between Velocity and Acceleration. There are 2 most important parameter velocity and acceleration related to the motion of different bodies. The main difference between these two parameters is that velocity changes in the position of a body in a specific direction in unit time. While acceleration is the change in velocity in a specific direction per unit time.
In today’s post, we will have a detailed look at different parameters of velocity and acceleration and find differences. So let’s get started with the Difference Between Velocity and Acceleration.
Difference Between Velocity and Acceleration
Velocity
- The variation in the position of a body in unit time is called velocity.
- Its measuring formula is a meter per second.
- The rate of change in the position of the body with time is called velocity.
- It is equivalent to the body speed feature having direction and movement.
- It mostly used in the science field of kinematics.
- It is a physical term has velocity tan magnitude.
- Its unit is m/s
- The velocity measured between two objects called relative velocity.
- Its dimension is LT−1
- The moving body has zero value of speed
- A change in velocity called acceleration
- Speed measured at any instant of moving object is called instantaneous speed
- The product of mass and velocity is equal to the momentum.
- Speed is related to the displacement of the body.
- It is also known as a change in displacement of the body.
Calculation of Velocity
Velocity can be measured by dividing the displacement of anybody by the time taken. The formula for calculating velocity is:
- v = s/t
where: v = velocity s = displacement t = time taken
What is Speed
- Speed is denoted with V and is the magnitude of variation in the position of anybody and it is a scalar term.
- The time duration in which the distance covered through the body parted in different parts is called average speed.
- The system international unit used for speed is a meter per second. In some cases, kilometers per hour is used
Difference between Speed and Velocity
- Speed tells about the motion of an object and the quantity of a moving object while velocity tells about the speed quantity and motion of direction.
- Let us tale an example car moving with a speed of thirty kilometers per second and its direction is toward south then its speed is given
Tangential Speed
- Tangential speed is caused due to the body moving in a circle.In this case, the direction of motion of the object lies at the tangent to the circle so it is called tangential speed
Acceleration
- The rate of change of velocity is called acceleration.
- The direction of acceleration is found through the total force acting at the body
- The magnitude of the acceleration is explained through the use of the second law of Newton
- Its meauring unit is m/s^2.
- The product of mass and acceleration is equal to the force.
- It is related to the velocity of the body.
Calculation of Acceleration
The formula for the calculation of acceleration is given here.
- a = (v-u)/t
where: a = acceleration v = final velocity u = initial velocity t = time taken
What is Uniform Acceleration
- The acceleration in which the velocity of any moving body varies through equal quantity in given time is called uniform acceleration.
Velocity Vs Acceleration
Velocity
- The change in displacement is called velocity.
- it is a vector that has direction and magnitude.
- Its formula is (d/t)
- It defines how fast the body is moving
- Its measuring unit is meter/second (m/s)
Acceleration
- The change in velocity is called acceleration and it is also a vector
- Its formula is (v/t)
- It defines how fast the velocity of the body varies
- It measuring unit is (m/s2)
Faqs
What is the relationship between speed and acceleration?
- Speed is the distance covered in unit time and acceleration is the rate of change of speed concerning certain direction
What are 5 examples of velocity?
- Earth’s rotation around the Sun,
- Moon’s orbital motion around the Earth.
- The river is moving at a varying speed.
- vehicle’s speed
- Train moving speed
Is velocity can be negative?
- If the body is moving in a positive direction velocity is positive and if the body is moving in a negative direction velocity is negative.
Are velocity and acceleration equal?
- Acceleration is the rate of change in velocity and velocity and displacement also have a relation. Velocity is change displacement. which means acceleration is the second derivative of displacement.
Does velocity cause acceleration?
- If the velocity of the body varies that means the body is in acceleration. Velocity measures both speed and direction. Since the change in velocity can be a change in how fast anybody is moving or changing movement direction.
Is velocity scalar or vector?
- Velocity is a vector quantity and it is defined as displacement in unit time. As velocity is a vector and the direction of velocity is like displacement.
What are the 4 types of velocity?
- Uniform velocity
- variable velocity
- average velocity
- instantaneous velocity
What is the main difference between speed and velocity?
- Speed is defined time rate with which the body is moving in a certain path and velocity is the rate and direction of the body.
- Speed is scalar and velocity is vector.
What are the 4 formulas for velocity?
Variable | Equation |
Velocity | v=u+at |
positive acceleration | s=ut+21at2 |
initial and final velocities | s=21(u+v)t |
Velocity squared | v2=u2+2as |
