Asteroids have a constant speed in a vacuum if there isnt anything else affecting it such as gravity or by colliding with other things. If it was to be in the earths atmosphere then the air would cause a resistance and slow it down :) hope this helps
Constant is the speed of light and as the speed of light cannot change it is 'constant'
No. Velocity includes a direction vector, which speed does not have.
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.
Acceleration by definition is a change in speed, direction, or both. If the speed is constant, the direction could still be changing. You can feel a change in direction, therefore you can feel acceleration even if the speed is constant.
it means the object is moving at a constant speed
constant velocity is when you maintain speed and direction, this usually is in a straight line, and constant speed means that your speed is always constant at all times.
Yes. If an object is moving at a constant speed the average speed and the constant speed are the same.
Constant is the speed of light and as the speed of light cannot change it is 'constant'
No. Velocity has two parts, speed and direction A constant velocity means that both the speed and the direction must be constant. So a constant velocity must have a constant speed.
non-constant speed is when the speed for an object does not stay the same
non-constant speed is when the speed for an object does not stay the same
If speed does not change then the object is moving with constant speed. when object moves in a circle its speed does not remains constant. Speed of object remains constant only if it moves along linear path.
Unless the train is in a curve, you cannot have constant speed and constant acceleration. You either have constant speed and zero acceleration, or you have changing speed and constant acceleration. Please restate the question.
Constant speed is constant velocity which means your going a certain speed in a straight line. Speed is just your speed at an exact moment also called instantaneous speed
distance = speed x time.This assumes a constant speed.distance = speed x time.This assumes a constant speed.distance = speed x time.This assumes a constant speed.distance = speed x time.This assumes a constant speed.
Yes, speed is the scalar of velocity.
Constant speed means that speed doesn't change. Constant acceleration means that acceleration doesn't change. (If the acceleration is anything but zero, speed WILL change.)
