What is the maximum displacement?
Amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path.
What is an example of distance and displacement?
E.g.: if a car travels east for 5 km and takes a turn to travel north for another 8 km, the total distance travelled by car shall be 13 km. The distance can never be zero or negative and it is always more than the displacement of the object.
Is it possible to have negative value in speed and displacement?
Explanation: Speed have never negative value because it is a scalar quantity and does not have direction. Whereas displacement have negative value because it is vector quantity then it has both magnitude and direction ,so displacement can be negative, positive and zero also.
Can speed be negative or zero?
Speed = Distance travelled/Time taken The ratio of distance travelled and the time taken by a body can be zero but not negative. Since distance and time are positive quantities and speed is obtained by the ratio of these two quantities, speed cannot be negative.
Can a body have constant speed and variable velocity?
Yes, a body can have constant speed but variable velocity. For example, a body in uniform circular motion has constant speed but its velocity changes at every point during the course of motion. Whenever, the direction changes, velcoity changes.
Can a body have constant velocity?
No, a body can not have its velocity constant, while its speed varies. Rather, it can have its speed constant and its velocity varying. For example in a uniform circular motion.
Does velocity change in circular motion?
To summarize, an object moving in uniform circular motion is moving around the perimeter of the circle with a constant speed. While the speed of the object is constant, its velocity is changing. Velocity, being a vector, has a constant magnitude but a changing direction.
Can an object accelerate if its velocity is constant?
An object’s acceleration is the rate its velocity (speed and direction) changes. Therefore, an object can accelerate even if its speed is constant – if its direction changes. If an object’s velocity is constant, however, its acceleration will be zero. Since it travels in a straight line, its direction does not change.
Do you notice any relation between the velocity 2 radius and acceleration?
Do you notice any relation between the velocity^2, radius, and acceleration? Acceleration increases as velocity increases, and it decreases as velocity decreases. As radius increases, acceleration decreases, and as it decreases, acceleration increases. So a = v^2/ r.
What is relation between linear velocity and angular velocity?
The greater the rotation angle in a given amount of time, the greater the angular velocity. Angular velocity ω is analogous to linear velocity v. We can write the relationship between linear velocity and angular velocity in two different ways: v=rω or ω=v/r.
What is the formula for linear velocity?
The linear velocity v of the point P is the distance it traveled divided by the time elapsed. That is, v=st. The distance s is the arc length and we know that s=rθ.
Is angular velocity dependent on radius?
Linear/tangential velocity, in a circlular path, increases with the increase in radius and decreases with the decrease in radius. Hence, the angular velocity remains the same no matter what the change in radius is(W=V/r).
What is the relation between linear velocity V and angular velocity ω explain with proper diagram?
From the knowledge of circular motion, we can say that the magnitude of the linear velocity of a particle travelling in a circle relates to the angular velocity of the particle ω by the relation υ/ω= r, where r denotes the radius. At any instant, the relation v/ r = ω applies to every particle that has a rigid body.
Which of the following is the correct relation between linear velocity?
v =ω ×r.
What is the relationship between linear and angular displacement?
What the equation and illustration below demonstrates is that linear displacement of any point on a rotating body is proportional to the radius of rotation (r; distance that point is from axis of rotation) and the angular displacement of the rotating body.
