Forces and Motion: Basics

  • Identify when forces are balanced vs unbalanced.
  • Determine the sum of forces (net force) on an object with more than one force on it.
  • Predict the motion of an object with zero net force.
  • Predict the direction of motion given a combination of forces.

Projectile Motion

  • Determine how each parameter (initial height, initial angle, initial speed, mass, diameter, and altitude) affects the trajectory of an object, with and without air resistance.
  • Predict how varying the initial conditions will affect a projectile’s path, and provide an explanation for the prediction.
  • Estimate where an object will land, given its initial conditions.
  • Determine that the x and y motion of a projectile are independent.
  • Investigate the variables that affect the drag force.
  • Describe the the effect that the drag force has on the velocity and acceleration.
  • Discuss projectile motion using common vocabulary (such as: launch angle, initial speed, initial height, range, time).

Ramp: Forces and Motion

  • Predict, qualitatively, how an external force will affect the speed and direction of an object's motion.
  • Explain the effects with the help of a free body diagram.
  • Use free body diagrams to draw position, velocity, acceleration and force graphs and vice versa.
  • Explain how the graphs relate to one another.
  • Given a scenario or a graph, sketch all four graphs.
