# the rate at which velocity changes

the rate at which velocity changes is called acceleration Acceleration is the rate of change of velocity. It is measured in meters per second squared (m/s2). An object’s acceleration is the net result of any and all forces acting on the object, as described by Newton’s Second Law. The SI unit for acceleration is meter per second squared (m/s2).

Accelerations are vector quantities (they have magnitude and direction) and thus are described by both magnitude and direction. The acceleration of gravity, denoted g, is the acceleration caused by gravity. It is the free fall acceleration experienced by an object in a vacuum near the surface of the Earth. Its value is 9.8 m/s2. An object’s acceleration can be determined by measuring its velocity at different times. This is done using the formula: a = (v – u)/t, where v is the final velocity, u is the initial velocity, and t is the time taken for the change in velocity to occur. The SI unit of acceleration is meter per second squared (m/s2). The cgs unit of acceleration is gal, or cm/s2. An object’s acceleration can also be determined by measuring its change in momentum over time.

The SI unit of acceleration is meter per second squared (m/s2). The cgs unit of acceleration is dyne, or cm/s2. There are two types of acceleration: linear and angular.

Contact forces are those that act on an object when it is in contact with another object. Action-at-a-distance forces are those that act on an object without any physical contact. The SI unit of force is newton (N). The cgs unit of force is dyne (dyn). The net force on an object is the vector sum of all the forces acting on it. The SI unit of torque is newton meter (Nm).
