How would one describe the acceleration (linear and angular) if the velocity is constant but direction is constantly changing, i.e., circular motion?
Acceleration is the rate at which the velocity of an object changes over time. It can be defined as the change in velocity divided by the change in time.
Velocity is a vector quantity that describes the speed and direction of an object's motion, while acceleration is a vector quantity that describes the rate at which the velocity is changing.
Acceleration is caused by a force acting on an object. This force can come from various sources, such as gravity, friction, or an applied force.
The unit of acceleration is meters per second squared (m/s^2) in the International System of Units (SI). It can also be expressed in other units, such as feet per second squared (ft/s^2) or kilometers per hour squared (km/h^2).
Acceleration can be measured using a device called an accelerometer, which measures the change in velocity over a specific period of time. It can also be calculated using the equation a = (vf - vi)/t, where vf is the final velocity, vi is the initial velocity, and t is the time interval.
