MOTION

Nota:

• motion is a change in position of an object with respect to time and its reference point. Motion is typically described in terms of displacement, direction, velocity, acceleration, and time.

Nota:

• Is the quantity that tells us how quickly bodies change their position: it refers to the distance travelled in a specific time

1. Constant Speed
   1. Uniform Rectilinear Motion URM

      Nota:

      • is motion along a straight line, and can therefore be described mathematically using only one spatial dimension. The linear motion has constant velocity or zero acceleration;

• Trajectory Distance travelled Displacement Speed Average speed Uniform Rectilinear Motion Acceleration Uniformly accelerated rectilinear motion Graps

• Geometric line that a moving object describes

1. Changing Speed
   1. Acceleration

      Nota:

      • Is the rate at which the velocity of an object changes over time.
      1. Positive
      2. Negative
   2. Uniformly Accelerated Rectilinear Motion UARM

      Nota:

      • Is motion along a straight line, and can therefore be described mathematically using only one spatial dimension.   It has variable velocity or non-zero acceleration.
