Motion

• What is the difference between displacement and distance?

  Distance is the total length of the path traveled, while displacement is the change in position from the starting point to the ending point.
• Define acceleration in terms of velocity and time.

  A= Change in V / time
• What does the term ‘uniform acceleration‘ mean?

  Constant
• What does the gradient for

  a.) Distance-time graph

  b.) velocity-time graph?

  a= speed

  b= the displacement of a moving object
• What is terminal velocity? What causes it?

  The maximum velocity an object can reach while falling through a fluid, such as air. Gravity and aerodynamics
• State newtons three laws of motion:

  1. An object will remain at rest or in motion unless acted upon by a resultant force
  2. F=ma
  3. for every action there is an equal and opposite reaction
• What is inertia?

  Resistance to change in motion.
