What are the similarities and differences between speed and velocity?

What are the similarities and differences between speed and velocity?

Physics

Speed, velocity and acceleration these three words are well introduced with us in class 9. All the three words speed, velocity and acceleration has some similarities and differences between them. We have discussed it on later part of the articles. But before we proceed with relation, similarities and differences between these three terms. we have to keep in mind a rough idea about speed, velocity and acceleration. So lets start with Speed.

What is speed?

Speed is defined as the actual path covered by the body in every direction with respect to time consumed by the body in every aspect of positions is called speed.

• It is scalar quantity.
• It has no direction.
• speed is denoted by 'S'.
• Generally seed is measured by m/s or km/hr.
• So, S.I unit of speed is m/s.
• C.G.S unit of speed is cm/s.
• It depends on the actual path of the body weather it may be curve or straight.

What is velocity?

Velocity is defined as the shortest distance (called as displacement) travelled by the body with respect of every point of time is called velocity.

• It is vector quantity.
• It has magnitude as well as direction.
• velocity doesn't depends on the actual path covered by the body.
• It's value depends on the direction in which body has travelled.
• S.I unit of velocity is m/s or km/hr.
• C.G.S unit of speed is cm/s.
• It depends on the straight line path not curved or actual path.
• Velocity is denoted by 'V'.
• It is of two types ''Initial velocity(u) and Final velocity(v)''.

What is acceleration?

Acceleration is defined as the rate of change of velocity with respect of time is called acceleration. It is of two types first is uniform acceleration and second is non-uniform acceleration.

• S.I unit of acceleration is m/s2.
• It is vector quantity.
• It has both direction and speed.
• Acceleration doesn't depends on the actual path covered by the body.
• It's value depends on the direction in which body has travelled.
• C.G.S unit of acceleration is m/s2.
• It is denoted by 'A'.
• It is of two types Uniform acceleration and non-uniform acceleration.

Similarities and differences between speed and velocity

• The similarities between speed and velocity is that both have same S.I unit m/s.
• The similarities between speed and velocity is that both are measured in same unit.
• The similarities between speed and velocity is that both may have been positive value.
• The differences between speed and velocity is that speed doesn't depends on nature of the path but velocity depends on the nature of the path.
• The differences between speed and velocity is that speed is scalar but velocity is vector quantity.
• The differences between speed and velocity is that speed is distance respect of time but velocity is displacement respect of time.
• Speed is denoted by ''s'' but velocity is denoted by ''v''.
• Speed is only one type but velocity is of two types.
• Speed can never be zero but velocity can be zero.
• Speed can never be negative but velocity can be negative.

People also ask

What is the difference between the velocity and speed of an object moving in a straight line?

Ans:- The difference between speed and velocity of an object moving in a straight line is that if a body returns to their initial stage from where he started, then velocity will be zero due to the displacement will be zero. but speed will not be zero.

What are the similarities and differences between speed velocity and acceleration?

Ans:- 

• The similarities between speed velocity and acceleration is that all the three terms may have a positive value.
• The differences between speed velocity and acceleration is that speed can never be zero and negative but velocity and acceleration may be negative and zero.

• The biggest disadvantages of digital life is that when we spend a lots of time in our phone then some of the chemical releases in our body in a big amount which is not good for our health.

Short essay on digital life

Digital life is both blessing or curse for us. We use mobile phone, desktops, laptop etc for short term pleasure. But in real it gives us nothing. According to the report a maximum of people spent an average of 4 to 5 hours a day in their smart phone. So there is a famous quotes ''we should use a smart phone smartly''. The best way to live a digital life is that ''Rather than to be a consumer, be a creator''.

What do we call the region of a sound wave where the molecules are spread out?

What do we call the region of a sound wave where the molecules are spread out?

Physics

What do we call the region of a sound wave where the molecules are spread out?

As we know that sound wave travels through a material medium (medium which consists of particles). But do you know how this particles of the medium helps the wave to propagate and travels through it. Lets see.

When any objects or body makes or produces sound. It travels through a material medium, present there. A disturbance produces in a medium which is in fixed pattern. Depending on the types of the medium the disturbance produces in different-different ways. 

But here we only talk about longitudinal or transverse wave. which mostly used in the propagation of a sound wave.

 

When a sound wave travels through a material medium. It produces a fix pattern disturbance in the particles of that medium. And those pattern are in two different ways in two different region. first region are closed particles and second one is spread out particles. Hence compression are that region of a sound wave where the molecules are closed and we call rarefaction of that region of a sound wave where the molecules are spread out. see given fig.

we have different-different questions in our mind like

• When sound waves bend and spread out it is called?

Answer: compression and rarefaction.

• What is the spreading of waves called?

Answer: Rarefaction

• What is the name for the region in a sound wave where the particles are further apart than normal?

Answer: Further apart sound wave are called Rarefaction and Normal sound wave are called compression. But remember that are not normal, it has compressed a little.

Hence, the answer of all the above questions are same. That is compression and rarefaction.

Is sound a wave or a particle?

Is sound a wave or a particle?

Physics

Is sound a wave or a particle?

Sound is that sensation of a object or body that makes senses of hearing. In other words sound is the vibrating particles that is created by the disturbance in a medium.

The answer is sound is ofcourse a wave that needs a metrial medium which consists of some particles for the propagation of sound wave. That's why sound cannot travel through vaccum. Because in vaccum there is no any presence of particles and air.

Hence, we conclude that sound is a wave not particles. Particles only helps to propagate sound wave. Not sound itself a particles.
