# Physics 1401 problems about rotaional Motion and angular displacement and angular velocity and angular accelration about height problems?

no one can help me

### When the velocity of the body is doubled its acceleration?

when the velocity is doubled then its accelration is also doubled.because a=v/t

### What is the relationship between displacement and velocity?

velocity = displacement / time taken

### If the displacement is zero then is the average velocity also zero?

Average velocity is zero if the displacement is zero. Average velocity = Displacement/Time = 0/Time = 0.

### Is displacement directly proportional to velocity?

No. Distance is, but displacement has no direct relation to velocity.

### How do you you find displacement from velocity?

Velocity is defined as v = dx/dt where: v is velocity; dx is displacement; and dt is elapsed time. Assuming velocity is constant, then displacement is calculated as: dx = v/dt.

### If displacement is not changing as a function of time then what can we say about velocity?

If the displacement is not changing, the velocity is zero.

### What is the formula for calculating displacement in which initial velocity and time are the variables?

If the velocity is constant, then Displacement = (initial velocity) multiplied by (time)

### Does a steep slope on a displacement vs time graph indicates a very large velocity?

Yes it does. Velocity = Displacement / Time. On a graph of displacement vs time, the slope is the velocity. Steeper slope = higher velocity, flatter slope = lower velocity.

### Expression for velocity?

velocity is the rate of displacement. That is velocity = displacement/time. In kinematics there are number of expressions for velocity, some of them are 1) v = u + at 2) v^2 =u^ 2 + 2as , where u - initial velocity, v - final velocity, s - displacement and a - acceleration.

### Equation for calculating average velocity from displacement and time interval?

a=dv/dt average velocity = displacement divided by time take. so average velocity = displacement/time taken.

### What is the average velocity of the particle from rest to 15 seconds?

To find average velocity, you need to know the displacement. If you knew displacement, average velocity would be found by: V = Displacement / time

### How do you find displacement on a velocity-time graph?

how to calculate displacement on a velocity time graph

### What does the term velocity mean?

Velocity is the time rate of change of displacement or the rate of change of displacement.

### How do you calculate the velocity?

Displacement/time * * * * * Velocity is a vector so the direction of displacement needs to be specified.

### Identify the two pieces of information you need to know the velocity of an object?

Displacement and Time, displacement is the distance with a direction ( vector quantity) , and time . Displacement and velocity are directly proportional, while velocity and time are inversely proportional..( The faster, the less time it will take) Velocity = Displacement ____________ Time

### How can you find initial velocity when the displacement is given but time is not?

Assuming you also know the final velocity and acceleration over the displacement then the initial velocity is Vinitial = (Vfinal2 - 2*acceleration*displacement)0.5

### How do you find displacement when you only have acceleration initial velocity and final velocity?

Kinematics. Final velocity squared = initial velocity squared + 2(gravitational acceleration)(displacement)

### What is relation between displacement and time?

Velocity is the displacement per unit time. V =dx/dt Note velocity and displacement are vectors and have direction.

### How do you figure displacement?

A displacement is the shortest distance measured .IT is measured in unit of length and distance .But ,,instead of speed velocity is used . Displacement = velocity /time.

### What equals the displacement on a velocity time graph?

The displacement on a velocity-time graph is the area beneath the line.

### What is describe velocity?

velocity is displacement / time. Displacement is shortest distance between initial and final point

### Can you cite an example in which the accelration of a body is opposite in direction to its velocity?

An example in which the acceleration of a body is opposite in direction to its velocity is a car slowing down. This is called negative acceleration, or deceleration.

### How do you figure out velocity?

Velocity is displacement divided by time. Displacement is different from distance traveled, as displacement states how far you traveled in RELATION to a starting point. The formula for Velocity is ---- v = x / t v = Velocity x = Displacement t = Time velocity is a vector quantity so the direction should also be specified unless it is implicit in the problem. ----

### How velocity of an object can affect its work?

work is the product of force and displacement As velocity is rate of change of displacement, so yes, velocity does effect work.

### How the displacement of a vertically thrown ball varies with time?

It is converted to the ball's velocity or it is known as its velocity because displacement changes with time is known as velocity.

### Is drift velocity the velocity of an electron or its displacement?

It is type of velocity of electron.

### What are the practical applications of Angular Speed Angular Displacement Angular Velocity and Angular Momentum?

These are used in lots of engineering problems related to rotation.

### Can the equations of kinematics be used in a situation where the acceleration varies in time can they be used when the acceleration is zero?

Yes the equations of Kinematics can be used if accelration varies with time, displacement or even velocity; but remember it's not just plug & chug, you will have to integrate the equations. vdv=ads ds/dt=v dv/dt=a d2s/dt=a

### When the average velocity of an object equals zero what is the displacement of the object?

When the velocity is zero at the crossing of the time axis, the displacement must be a full maximum or minimum. Scroll down to related links and look at "Displacement - Velocity- Acceleration".

### What equation can be used to find velocity when you have displacement?

v = Δdt / Δt Average velocity = Total displacement / time If you want to be more specific: v = ds/dt Instantaneous velocity = derivative of displacement with regard to time

### How do you achieve negative velocity?

If you have a Displacement - time graph, the velocity at a certain point equals displacement over time, displacement is a vector quantity thus is affected by direction so when it has a negative value the velocity has a negative value. and if your still thinking about it, check out this thought: "negative velocity is positive velocity in the other direction"

### How do you get velocity using mass and displacement?

You don't. Velocity is not directly related to mass, and you can't calculate velocity just from a displacement measurement. You need some more information.

### If the total displacement is zero can the average velocity be nonzero?

No, you cannot have a zero displacement and a nonzero average velocity. If the object has not moved any where how can you attain a nonzero velocity? You cannot.

### Difference between instantaneous and average velocity?

Average velocity is simply displacement over time. Instantaneous velocity is the velocity at any given instant, or the displacement over an infinitely small amount of time.

### Can there be zero displacement and nonzero average velocity?

It is not possible because the average velocity is equal to the displacement in a given time interval, ie: V = (displacement) / (time interval) As the zero displacement average speed will also be zero.

### What is differentation?

Velocity is the rate of change in displacement. velocity = d(displacement)/d(time) You could also describe it as 'the rate of change'

### How do you find displacement from velocity and time?

d=displacement v=velocity t=time d/t=v tv=d

### Velocity is the slope of a displacement vs time graph true or false?

It is true that velocity is the slope of a displacement vs time graph.

### How do you get the velocity?

Velocity is derived by dividing displacement with time in seconds

### What is the scientific formula for displacement?

scientific formula for displacement = velocity Xtime
