What is the velocity of an object moving at constant velocity?
Constant velocity means that the object in motion is moving in a straight line at a constant speed. This line can be represented algebraically as: x=x0+vt x = x 0 + vt , where x0 represents the position of the object at t=0 , and the slope of the line indicates the object’s speed.
What is the acceleration of an object that moves with constant velocity?
zero acceleration
If an object is moving with a constant velocity, then by definition it has zero acceleration. So there is no net force acting on the object. The total work done on the object is thus 0 (that’s not to say that there isn’t work done by individual forces on the object, but the sum is 0 ).
What happens to acceleration when there is constant velocity?
Acceleration is the change in velocity during a given period of time. Any time there is a change in velocity or the direction of motion acceleration has occurred. At constant velocity acceleration is equal to zero.
Can the velocity of a car change when its speed is constant?
yes by changing direction. Velocity is a vector with a magnitude equal to the speed and a direction. If the direction changes, then the velocity changes even though the speed is constant. When you drive around a curve at constant speed, you are changing velocity and can feel the acceleration in your body.
What acceleration is produced by a 3000N force on a 1000 kg car?
here, m=1000kg and a=3m/s2 . hence, the force needed to accelerate the 1000kg car by 3m/s2 is 3000N .
Can you move with constant speed and not constant velocity?
Is it possible to move with constant velocity but not constant speed? The answer to the first question is yes. Velocity means speed and direction, if the velocity is constant, then that means both speed and direction are constant. …
Can you move at constant velocity without moving at constant speed?
No, it doesn’t. Velocity is a vectorial quantity, it has magnitude (speed) and direction. Uniform circular motion can be given as an example in order to help you with your question. Even though the speed is constant in this particular example, the direction changes all the time.
Is car constant constant or velocity?
Car 1 – Position and velocity graphs Constant velocity means the velocity graph is horizontal, equal to 11.11 m/s at all times. A constant velocity means the position graph has a constant slope (of 11.11 m/s). It’s a straight line sloping up, and starting below the origin.
