If the velocity is constant, it follows that the the sum of all forces on the ice skater is zero.
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.
Such and object is said to be in equilibrium. No acceleration and no force.
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.
"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.
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.
If constant motion means constant velocity then, total distance / total time = avg velocity => avg speed constant velocity => avg velocity = velocity
If you have eliminated all resistance then the initial force will be enough.
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.
It is motion in a straight line at 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.
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.
It can be in equilibrium if in constant motion (constant velocity) as no forces are acting on it (no acceleration)
Objects moving in uniform circular motion will have a constant speed, and two objects with the same acceleration have a constant velocity.
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.
the object is on uniform motion
he do not do any motion
No. The direction keeps changing. Constant velocity means constant speed in a straight line.
