define the following terms used in motion

Question

1. distance
2.speed
3.displacement
4.velocity
5.acceleration

Answer 1

1. Distance: The total length of path covered by an object in motion. It is a scalar quantity and is measured in units such as meters or kilometers.

2. Speed: The rate at which an object covers a distance. It is the magnitude of the velocity vector and is a scalar quantity. Speed is calculated by dividing the distance traveled by the time taken to cover that distance. It is measured in units such as meters per second or kilometers per hour.

3. Displacement: The change in position of an object in motion. It is a vector quantity and is calculated by subtracting the initial position from the final position of the object. Displacement takes into account both the distance and direction of the movement.

4. Velocity: The rate at which an object changes its position. It is a vector quantity that includes both speed and direction. Velocity is calculated by dividing the displacement of an object by the time taken to make that displacement. It is measured in units such as meters per second or kilometers per hour.

5. Acceleration: The rate at which an object's velocity changes over time. It is a vector quantity that includes both magnitude and direction. Acceleration is calculated by dividing the change in velocity by the time taken for that change to occur. It is measured in units such as meters per second squared.
