Learning Objectives
Calculate average velocity and average acceleration of an object
Interpret graphs of motion (expected knowledge from Year 11)
Use kinematic equations to calculate instantaneous vi, vf, a, t, and d.
Explain the motion of objects in free-fall
Solve problems with objects that are experiencing horizontal projectile motion
Velocity & Acceleration
Velocity & Acceleration
This will be a recap of previous years' learning.
Videos of concept
What is acceleration (5mins) note that this person uses the symbols u for initial velocity and v for final velocity. We usually use vi for initial velocity and vf for final velocity
Graphs of Motion
Graphs of Motion
This will be a recap of previous years' learning.
In Year 11 there was a large focus on motion graphs. We do not see these often in Year 12. HOWEVER, you ARE expected to know how to interpret them if one ever came up.
Remember: In NCEA Level 2 acceleration will always be constant.
