Is there a relationship between speed and acceleration?
Speed is the distance covered in a unit of time while acceleration is the rate of change of speed. The unit of speed in the metric system is meters per second (m/s) while that of acceleration is meters per second squared (m/s2). Speed is a scalar quantity while acceleration is a vector quantity.
How can you tell if a statement is speed or velocity?
Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement. Put another way, speed is a scalar value, while velocity is a vector.
What is the computed value of the velocity?
Answer: Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.
When can the speed and velocity of a moving body be equal?
Answer. magnitude of velocity and speed of a moving body will be equal when magnitude of displacement and distance will be equal respectively .
Can the speed of a body change if velocity is constant under which condition distance and displacement are numerically equal?
Therefore the average speed and average velocity are equal if the total displacement is equal to the total distance that is if the body travels along a straight line without changing the direction.
What is the body’s two speed and velocity?
There are Two Types of Speed: Uniform Speed: When the distance travelled by a body is equal in equal interval of time then the speed is uniform….Speed & Velocity.
| Speed | Velocity |
|---|---|
| Speed ascertains how fast a body moves. | Velocity ascertains the object’s speed and the direction it takes while moving. |
What two cases do speed and velocity of an object become the same?
We can only say that velocity and speed of a particle are identical when the particle does not changes its direction and possesses a particular magnitude in that particular direction I.e. in simple words when particle goes in one direction and does not changes its path.
What is the difference between the velocity and speed of an object moving in a straight line?
What is the difference between the velocity and speed of an object moving in a straight line? Velocity can be positive or negative, depending on the direction the object is traveling. Speed is always negative.
Why is tangential acceleration?
The tangential component occurs because of the change in the speed of traversal. It points along the curve in the direction of the velocity vector; also in the opposite direction. Henceforth, it always acts in the perpendicular direction to the centripetal acceleration of a rotating object.
