How is speed calculated?
What is the definition of acceleration in physics?
Parameters Used to Describe Motion
In physics, the parameters used to describe motion are distance (d) and time (t). Distance is measured in meters or feet, while time is measured in seconds, minutes, or hours.
Scalars vs. Vectors
Scalars are parameters without a direction, such as speed, while vectors include direction, such as velocity (e.g. 16 m/s east).
Calculating Speed
Speed is calculated by dividing the distance covered by an object (d) by the time taken to cover that distance (t). The formula for speed is v=d/t or v=(d2-d1)/(t2-t1).
Definition of Acceleration
Acceleration in physics is defined as the rate of change of velocity with respect to time. It can be positive (speeding up) or negative (slowing down) and is calculated as a=v/t or a=(v2-v1)/(t2-t1).
In physics, the study of motion involves understanding various parameters that help describe the movement of objects. Distance and time are key parameters used to quantify and define motion. Distance is the measurement of how far an object has traveled, typically measured in meters or feet. Time, on the other hand, quantifies the duration of movement and is measured in seconds, minutes, or hours.
