No, the absolute value of speed does not equal velocity. Speed is a scalar quantity that represents the rate at which an object is moving, while velocity is a vector quantity that includes both speed and direction. The absolute value of velocity is the speed of the object.

When can an object a constant speed but not a constant velocity?
An object can move at a constant speed but not at a constant velocity when its direction is changing while its speed remains the same. This can happen if the object is moving in a circular path or if it is changing direction at irregular intervals. Constant speed refers to the magnitude of velocity remaining constant, while velocity includes both speed and direction.
Is it possible to have a changing velocity and a constant speed?
No, velocity includes both speed and direction. If the velocity is changing, it means either the speed, the direction, or both are changing. Constant speed means the object is moving at the same rate without speeding up or slowing down.
How does the mass and speed of an object affect the kinetic energy?
Kinetic Energy is 1/2 mass x the square of speed (KE = 1/2 mv^2)
What is kinetic energy versus square velocity?
Kinetic energy is the energy possessed by an object due to its motion, given by the formula KE = 0.5 * mass * velocity^2. Square velocity refers to the squared value of the velocity of an object. Since kinetic energy is directly proportional to the square of velocity, a small increase in velocity can result in a larger increase in kinetic energy.
If the mass of a moving object is doubled with no change in velocity what would be the change in momentum?
If the mass of a moving object is doubled with no change in velocity, the momentum of the object would also double. This is because momentum is directly proportional to mass (p = mv), so doubling the mass will result in a doubling of momentum as long as velocity remains constant.
Why is the absolute value of velocity speed?
It's a scrambled equation. What you meant to say is, "The absolute value of velocity equals speed."
Is it true or false that absolute value of speed equals velocity?
no
Why is the absolute value of speed equal to velocity?
It's not. Unless you add a direction to speed it will not become velocity. Since positive and negative are sometimes used to denote direction, absolute value of velocity may equal speed (certain situations)
Why is the value of velocity equal to speed?
This is because speed is defined as the absolute value of velocity - irrespective of the direction of motion.
Is absolute value of velocity is equal to speed?
Ye.s
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.
Is speed equal to velocity?
Velocity is a vector, which means it has a direction, but speed isn't. Speed is the absolute value of velocity. Velocity can be negative, meaning that the speed is opposite to the direction that you're calling the positive direction.
Can your speed and velocity ever have the same magnitude?
Speed and velocity always have the same magnitude, becausespeed is the magnitude of velocity.The difference is that velocity has a direction but speed doesn't
Formula for velocity and speed?
If s is the displacement vector of an object at time t, thenvelocity = ds/dt, the derivative of s with respect to tand speed = |ds/dt|, the absolute value of the velocity.
When acceleration is less than 0 and velocity is less than 0 then speed is?
When acceleration is less than 0 and velocity is less than 0, the speed is positive. Speed is the absolute value of velocity, so it is always positive regardless of the direction of motion.
What happens to the amount of distance an object travels when it speeds up?
The distance will increase as the speed (absolute value of velocity) increases.
If A car travels down the highway at 55 mph its speed is what and its acceleration is what?
Acceleration is zero since 55 mph is velocity and it is constant. Acceleration is defined as the rate of change in velocity. The speed is the absolute value of velocity so it is also 55.
