When can an object a constant speed but not a constant velocity?
If the velocity is constant there is no acceleration. Speed is not velocity, velocity has speed and direction. I A car going around a circular track at 60 mph keeps the same speed but changes direction and thus accelerates at a constant speed. Velocity is speed in a certain direction. So change the speed but keep direction the same and you change the velocity. or Change the direction while keeping the speed the same and you change the velocity. If the speed is constant, any change of direction is a change in velocity. Driving around in a circle is a case of constantly changing direction.
Is it possible to have a changing velocity and a constant speed?
Yes, the velocity of a constantly (or not constantly) accelerated object will vary. Velocity is distance per unit time with a vector. It's speed (distance per unit of time) in a given direction. Under constant acceleration, the velocity is changing at a constant rate. But the velocity is changing. It is varying. The object could be speeding up or it could be slowing down. Or it could be changing direction. Any of these change velocity. An object that is experiencing constant acceleration will have its velocity varying. Why wouldn't it have?
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 directly proportional to the square of an object's velocity. If you graph the object's kinetic energy against the square of its speed, the graph is a straight line, and the slope of the line is 1/2 of the object's mass.
If the mass of a moving object is doubled with no change in velocity what would be the change in momentum?
It doubles. Momentum (p) is the product of velocity (v) and mass (m). For a given mass, if you double the velocity, you'll double the momentum. Velocity and momentum are said to be directly proportional. p = m x v
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.
