and the metric unit for length.

Forces in Motion
 Know the concepts of motion, displacement, speed, velocity, acceleration, momentum, inertia, centripetal force,
gravity, force, action-reaction force, friction, free fall, air resistance, energy (and how it is measured), potential
energy (including SI unit), gravitational potential energy, kinetic energy, projectile motion and the law of
conservation of momentum.

Review how to distinguish between speed, acceleration and momentum graphs (see the test review for the 1st nine

Know the differences between instantaneous speed and constant speed; average speed and average velocity;
balanced and unbalanced forces; positive and negative acceleration; conservation of momentum and conservation
of energy, and the rate of acceleration due to gravity.
