  2. Unit # 1:Kinematics Big Ideas • Distance, displacement • Speed, velocity • Acceleration • Acceleration due to gravity

  3. Unit # 1: Kinematics An object travels 5 km [N], then 8 km [S], in 1200 seconds. a) Draw a diagram of the motion. b) Find the total distance travelled.

  4. Unit # 1:Kinematics c) Find the total displacement. d) Find the speed. e) Find the velocity.

  5. Unit # 1:Kinematics • How could you find the velocity from 0 s to 5 s? • How could you find the acceleration from 0 s to 5 s?

  6. Unit # 1:Kinematics A cyclist accelerates at a rate of 0.75 m/s2, from a speed of 1.5 m/s, for 7 seconds. Find their final speed. (4 marks)

  7. Unit # 2:Dynamics Big Ideas • Force of gravity • Free-body diagrams • Newton’s Laws, F = ma • Friction

  8. Unit # 2:Dynamics The acceleration due to gravity on the moon is 1.6 m/s2. Determine the force of gravity of an 80.0 kg astronaut standing on the moon. (3 marks)

  9. Unit # 2:Dynamics Draw a free-body diagram for a four-wheeler stuck in a swamp, that someone is trying to push out.

  10. Unit # 2:Dynamics Examine the free-body diagram below. If the car has a mass of 1200 kg, determine the acceleration of the object. Fn Ff = 37 N Fapp = 150 N Fg

  11. Unit # 2:Dynamics A 12 kg box is sitting on a table. The coefficient of kinetic friction is 0.44. Determine the force of kinetic friction on the box. What is the other type of friction? Would it be more or less than the kinetic friction?

  12. Unit # 3:Simple Machines Big Ideas • Simple Machines • Levers • Torque • Mechanical Advantage

  13. Unit # 3:Simple Machines A woman wants to raise one end of a piano so she can place coasters under the wheels. The piano has a weight of 1600 N, but the woman can only apply a force of 400 N. She places a fulcrum 30 cm from the piano and uses a strong board as a first class lever to raise the piano. a. Draw a sketch of this situation showing the fulcrum, the lever, effort arm, load arm, effort force and load force involved.

  14. Unit # 3:Simple Machines b. What is the length of the effort arm required to lift the piano?
