Acceleration is calculated by dividing the change in velocity by the change in time. This can be represented by the equation a = (vf - vi)/t, where a is acceleration, vf is final velocity, vi is initial velocity, and t is time.
The unit of acceleration is meters per second squared (m/s^2) in the SI system. It is also commonly expressed as feet per second squared (ft/s^2) in the imperial system.
The acceleration of an object can be measured using a device called an accelerometer. This device measures the rate of change in velocity and provides a numerical value for acceleration.
To find the acceleration of a moving object on a graph, you would need to calculate the slope of the line. The slope represents the change in velocity over the change in time, which is the definition of acceleration.
Yes, acceleration can be negative. A negative acceleration, also known as deceleration, means that the object is slowing down. This can occur when the object is moving in the opposite direction of its initial velocity, or when it is slowing down due to an external force.
