If the velocity is constant, it follows that the the sum of all forces on the ice skater is zero.

Why achanging velocity cannot maintaining constant speed?
A changing velocity can maintain constant speed if the motion is circular. The constant change in direction is a change in velocity, even if the speed is constant.
What is Motion without acceleration?
Such and object is said to be in equilibrium. No acceleration and no force.
What is difference between an object moving with uniform acceleration and an object moving with a constant velocity?
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
What is the Difference between Uniform motion and uniform acceleration?
"Uniform motion" means constant velocity ... constant speed in a straight line. "Acceleration" means any change in velocity ... speed or direction. So 'uniform motion' means zero acceleration.
Can an object have a constant speed and the varying velocity at the same time explain?
Velocity is a vector. A vector has a magnitude and a direction. The scalar or magnitude portion of velocity is speed. Velocity is a constant only when both the speed and direction are not varying. Hence, when the speed is changing, the velocity cannot be a constant.
How can you determine the speed of an object that has constant motion if you have a distance vs time graph of the motion?
If constant motion means constant velocity then, total distance / total time = avg velocity => avg speed constant velocity => avg velocity = velocity
If a hockey puck is set in motion across a frozen pond if ice friction plus air resistance are neglected the force required to keep the puck sliding at a constant velocity is?
If you have eliminated all resistance then the initial force will be enough.
If you slide a hockey puck across a frictionless ice rink these must be a horizontal force on it too keep it in the motion?
F=ma constant speed would mean 'a' acceleration is zero thus force zero. The puck would be in equilibrium, and the force would be zero at constant motion. Constant motion is constant velocity including the constant zero velocity.
What is a definition for the scientific term constant motion?
It is motion in a straight line at a constant velocity.
What is a motion with a constant velocity?
It is called uniform motion because the object covers equal distances in equal intervals of time which is why it has a constant velocity.
Does velocity of an object remain constant in uniform circular motion?
Velocity is a vector with magnitude (speed) and direction. Since the linear velocity changes direction the speed is constant but the velocity is NOT constant.
Can a body in equilibrium if it is in motion?
It can be in equilibrium if in constant motion (constant velocity) as no forces are acting on it (no acceleration)
What are two ways in which an object can have constant velocity uniform motion?
Objects moving in uniform circular motion will have a constant speed, and two objects with the same acceleration have a constant velocity.
Is motion with constant velocity an example of motion with constant acceleration?
Well, technically yes, and we even know the magnitude of the constant acceleration.If velocity is constant, that tells you that acceleration is zero, which sounds likea constant to us.
What is the motion of an object said to be if its velocity is constant?
the object is on uniform motion
What will the motion of the cart be like when there is no force at all?
he do not do any motion
In uniform circulation motion is the velocity constant?
No. The direction keeps changing. Constant velocity means constant speed in a straight line.
