PS.10 a - Speed, Velocity, & Acceleration

The student will investigate and understand the scientific principles of work, force, and motion. Key concepts include
a) speed, velocity, and acceleration.

Bloom's Levels:  Analyze; Understand

Adopted: 2010


  • Motion is a key characteristic of all matter that can be observed, described, and measured.
  • Energy change can be understood in terms of forces- pushes or pulls.

  • I can determine how fast a car is moving.
  • I can explain why, when two objects collide, they often bounce backwards.
  • I can explain why simple machines, such as a ramp (inclined plane), are useful.
  • I can design a roller coaster


  • Acceleration is the change in velocity per unit of time. An object moving with constant velocity has no acceleration. A decrease in velocity is negative acceleration or deceleration. A distance-time graph for acceleration is always a curve. Objects moving with circular motion are constantly accelerating because direction (and hence velocity) is constantly changing.


In order to meet this standard, it is expected that students will

a) make measurements to calculate the speed of a moving object.

     apply the concepts of speed, velocity, and acceleration when describing motion.

a-d) differentiate between mass and weight.
