motion in one direction
summary please
Answers
Motion is the displacement of an object from one place to another in time and space.
The physical quantities involved in describing motion are:
1. Displacement
2. Velocity
3. Acceleration
SCALARS AND VECTORS
Scalars are quantities that are fully described by magnitude alone (e.g., length, area, energy,
temperature).
Vectors are quantities that are fully described by both magnitude and direction (e.g.,
displacement, velocity, acceleration, momentum, force).
DISPLACEMENT
Displacement is defined as the change in position of an object.
Note: Displacement is not the same as distance.
It is a vector quantity given by:
∆x = xf – xi in meters (m)
xf is the final position of the object, in m
xi is the initial position of the object, in m.
