Webanother way that velocity can change is by changing its direction...even while its speed remains constant. This is the type of acceleration that will be explored in this chapter. A very important case of changing direction while maintaining constant speed is called uniform circular motion. WebAnswer (1 of 72): Velocity is a vector quntity that means it is dependent on both direction and magnitude. Speed is a scalar quantity that is it depends only on magnitude. So, A …

WebThis is a result of the law of conservation of energy, which says that, in a closed system, total energy is conserved—that is, it is constant. Using subscripts 1 and 2 to represent initial and final energy, this law is expressed as. K E 1 + P E 1 = K E 2 + P E 2. Either side equals the total mechanical energy. WebAug 30, 2006 · Ch 2 Review Answers: Velocity is speed plus direction. Velocity involves direction, but speed doesn't. No. If the speedometer always reads 40 km/h, you can say that the car had a constant speed, but not constant velocity.If the direction of the car changed - even at the same speed - then its velocity changed. swag hanging lamps with chain

WebAn acceleration can cause speed to increase, decrease, and even stay the same! Acceleration tells you the rate at which the velocity is changing. Because the velocity is a vector, you have to consider the changes to its magnitude and direction. The acceleration can change the magnitude and/or the direction of the velocity. WebMar 20, 2012 · The constant change in direction is a change in velocity, even if the speed is constant. Can a body have constant velocity when it has constant speed? Of course.
