The car undergoes a change in velocity. It accelerates (and does so at a constant rate - if the rate of turn is constant) in the direction of the turn. The speed is constant, but the direction the car is going changes at each instant in time because it is turning. And because it is changing direction, that means its velocity is changing (because velocity is speed plus a direction vector).
No. Circular motion can have constant speed but varying velocity. Constant speed means constant speed in any direction, like a car on cruise control turning a corner. Constant velocity means constant speed in a straight line. If the direction changes, that's considered a change in velocity.
If there be no force ie no deceleration then no need to apply any force to compensate such a deceleration. But deceleration is there due to frictional force between the tyre and the road. Hence to compensate this we have apply acceleration. So force is needed OK Physics laws State that an object in motion will remain in motion until acted upon by an outside force. The car moving at a constant speed is being acted upon by wind resistance, gravity, and friction. Therefore force is needed to retain the constant speed
If the speed is constant then equal distances are covered in equal intervals of time If acceleration is constant then equal change in velocity occurs in equal intervals of time.
You don't need to "propel" something, once it is already moving. The natural tendency is for a moving object to continue moving. It requires a force to STOP a moving object, but not to keep it moving at a constant speed. Now, light behaves not just as a particle (photon) but also as a wave; but I believe that the general principle is still the same.
Synchronous motors are those that run only at Synchronous speed ie.. constant speed.
Velocity is Speed in a given direction. Moving at constant velocity is equivalent to say moving with a constant speed in a specified direction. So, moving at constant velocity implicitly means moving with constant speed.
No, acceleration is a change in velocity. When a cyclist is moving at a constant speed around a corner, the direction of their velocity changes but not its magnitude, so there is no acceleration in the direction of motion. There may be a centripetal acceleration towards the center of the curve to keep the cyclist moving in a circular path.
The word is "stationary" for not moving, and "constant velocity" for moving at a constant speed in the same direction.
Yes, average speed can be used to calculate the speed of an object moving at a constant speed. This is because the average speed over a whole journey for an object moving at a constant speed is the same as its actual speed.
determine if the momentum of an object moving in a circular path at constant speed is constant.
determine if the momentum of an object moving in a circular path at constant speed is constant.
it means the object is moving at a constant speed
When the velocity of a moving object stays the same, it has a constant speed.
Moving at a constant speed means there is a consistent rate of motion, while not moving at all indicates no change in position. Both scenarios involve no acceleration, but in the case of constant speed, there is still ongoing motion, whereas not moving at all implies stationary position.
yes an acceleration is a change in speed and when you go around a corner you change your speed.
Yes, an object can have a constant speed but varying velocity if it changes direction while moving at that speed. Velocity includes both speed and direction, so if an object is moving in a straight line at a constant speed but changing direction, then its velocity is constantly changing even though its speed remains the same.
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.
