Particle model of matter

The particle model of matter is one of the most useful scientific models because it describes matter in all three states. Understanding how the particles of matter behave is vital if we hope to understand science!

The model also helps us to understand what happens to the particles when matter changes from one state to another.

Phases of matter

In this unit, you will explore the three phases of matter and then look at the properties and differences between them. You will explore their shape, volume, and kinetic energy.

Potential energy and position

The potential energy between two objects due to long-distance forces can be thought of as being stored in a field. When the objects move due to the field forces, the energy stored in the field decreases

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).
