Can change even when the speed is constant
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. 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 …

WebAcceleration is a change in velocity, either in its magnitude—i.e., speed—or in its direction, or both.In uniform circular motion, the direction of the velocity changes constantly, so there is always an associated acceleration, even … Webpublic speaking 561 views, 32 likes, 9 loves, 12 comments, 8 shares, Facebook Watch Videos from Wordlife Church, Ghana: GOOD FRIDAY SERVICE SPEAKER:...
WebFeb 1, 2024 · Hence just as the velocity is of constant magnitude (the speed) but constantly variable direction, so too the acceleration is also of constant magnitude but constantly variable direction (always at 90° to the motion). Because acceleration is a vector, just as velocity is, if you change the direction then you have changed it.
