What is a constant speed in physics?

Answer 1

I would guess what you mean by a constant speed is zero change in acceleration.

In the equation a = (v - u)/t

where a = acceleration, v = final velocity, u = initial velocity and t = time taken for this change to happen.

If your initial speed and final speed are the same (I.E. constant) then there is no acceleration.

Answer 2

Well it depends on what do you want to calculate if you want to calculate the kinetic energy at a certain instant then use 1/2*m*v^2 where m is the object's mass and v is its speed. However if you want to calculate the kinetic energy between two points then you will use delta kinetic =1/2*m*vf^2 - 1/2*m*vi^2 where vf and vi are the final and initial speed. In your case if you want to determine the change in kinetic energy for an object with constant speed then the answer would be zero. to be honest your question is not clear enough to give you definite answer.

Answer 3

KE = 1/2mv2, where m is mass in kg, and vis velocity in m/s. The equation for kinetic energy indicates a direct relationship between kinetic energy, mass, and velocity of an object. However if velocity is constant, the KE and mass are still directly proportional, so that the greater the mass of a particle, the greater its kinetic energy.

Answer 4

A constant speed in physics refers to the motion of an object where its velocity remains unchanged over time. This means the object is moving at a consistent rate without speeding up or slowing down. Mathematically, it is represented by a straight line on a distance-time graph.

Answer 5

depends. it can, for example, get converted to gravitational potential energy if the system reaches a higher altitude (ie something moving up a hill)
