  1. Acceleration Acceleration is the change in velocity divided by the time it takes for the change to occur. Like velocity, acceleration has a direction.

  2. Acceleration There are three ways an object can accelerate: Speeding up Slowing down Changing direction

  3. Summarize On your notes page, write down 5 times you have accelerated today. Compare answers with another person at your table. 

  4. Calculating Acceleration This is the formula for acceleration: acceleration = final speed – initial speed time In SI units, acceleration has units of meters per second squared (m/s2)

  5. Inertia Inertia = tendency of an object to resist a change in its motion. The greater an objects mass, the greater its inertia and the larger the force needed to overcome the inertia

  6. Inertia Examples: Inertia is the resistance you feel as you change the direction you are running on a field You can feel inertia when you catch a fast baseball that stings your hands as its momentum decreases abruptly to zero.

  7. Momentum Momentum = how hard it is to stop an object in motion. It depends on the object’s mass and velocity. momentum = mass (in kg) x velocity (in m/s)

  8. Activity You are now going to choose a sport and create a poster illustrating how momentum and inertia are important in that sport.

  9. Inertia = tendency of an object to resist a change in its motion. The greater an objects mass, the greater its inertia and the larger the force needed to overcome the inertia Momentum = how hard it is to stop an object in motion. It depends on the object’s mass and velocity. Momentum = mass x velocity
