What Has Direction Speed or Velocity?
Velocity has direction. Speed is a scalar quantity that only measures how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.
Does Light have a speed or a velocity speed of light or velocity of light?
Light travels at the speed of light. There is no general velocity of light because velocity is a vector quantity, it also contains a direction and there is no preferred direction for light rays in general. Another answer: The speed of light has been calculated to be 186,000 miles per second.
What is then net force if the velocity of an object is changing?
As velocity is changing that means acceleration/deceleration is taking place. Hence, Force will not be equal to zero. However, the direction of force will depend on the direction of velocity of body. So, it's not possible to predict whether the force will be positive or negative. The net force can not be found as the dimensions of body like mass and change in velocity are not given in the question.
Why is velocity a vector quantity?
Velocity refers to both speed and direction. A vector refers to both magnitude (the speed in this case) and a direction. Speed without reference to a direction is a scalar, a magnitude without direction.
Why is velocity tangential to the path of a body?
Velocity is a vector; having direction. So, when changing direction constatly to have velocity a tangent can be drawn to the constantly changing path of the object having velocity.
How is the absolute value of velocity speed?
Velocity is a vector and its magnitude depends on the direction. If it is positive in one direction, going in the opposite direction it is negative. But speed is a scalar and does not depend on the direction. It has the same value, whatever the direction. That is how the absolute value of velocity is speed.
Why does velocity not depend on distance?
Velocity is the rate at which an object changes its position, regardless of the distance it has traveled. Velocity considers both speed and direction, so a change in direction can affect velocity even if distance remains constant. Distance is the total length of the path traveled, whereas velocity focuses on the rate of change in position.
What is speed in a given direction is called?
Speed in a given direction is velocity.
What velocity do you get when you combine all the velocities?
When combining velocities in the same direction, you simply add them together. For velocities in opposite directions, you subtract them. The resulting velocity will depend on the direction and magnitudes of the individual velocities being combined.
Does momentum have a direction?
Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.
What is the velocity of a bus heading to Alpharetta traveling at 15 km in 4 10 minutes?
That's going to depend on where the bus leaves from, or ... what is equivalent ... what direction it has to head in order to get to Alpharetta. You can't talk about a velocity without a direction.
What is the direction of instantaneous acceleration?
The direction of instantaneous acceleration is in the direction of the change in velocity at that moment. If the velocity is increasing, the acceleration is in the same direction as the velocity. If the velocity is decreasing, the acceleration is in the opposite direction of the velocity.
What is speed in a given direction?
Speed in a given direction is called velocity.
Does the average speed depend on direction?
you know that i am your father and u are my son in the same way average velocity is your mother and velocity is your sister so go home u are drunk
What is the relationship between velocity direction and the motion of an object?
The velocity direction of an object indicates the direction in which it is moving. The motion of an object is determined by both its velocity magnitude (speed) and its velocity direction. The velocity direction influences the path the object takes as it moves.
Does constant speed depend on direction?
no,because speed is scalar which has magnitude only meanwhile velocity is vector which has magnitude and direction
What is the formula of velocity?
There are several definitions. not just one. Average velocity in a direction = Average displacement (distance) in that direction/time Instantaneous velocity in a direction = derivative of displacement in that direction with respect to time Average velocity in a direction = Initial velocity in that direction + Average acceleration in that direction * time Instantaneous velocity in a direction = Definite integral of acceleration in that direction with respect to time, with initial velocity at t = 0 Then there are others in which time is eliminated.
