WebOn Earth, we use the constant g = -9.8 m/s^2 to represent the constant acceleration due to gravity that pulls us to Earth's center of mass. Whether you use +g or -g depends on how you define your system; some people like to use +g and switch all their variables around. However, g always represents motion towards the center of Earth. Webobject (e.g. gravity) is balanced by frictional forces (e.g. air resistance). 29 Circular motion (HT) An object moving in a circle has constant speed but changing velocity. This is because the direction in which the object is moving is constantly changing, and velocity is a vector quantity that measures direction and speed.

It occurs when the sum of the drag force (Fd) and the buoyancy is equal to the downward force of gravity (FG) acting on the object. Since the net force on the object is zero, the object has zero acceleration. pinpoint learning login student maths
