Projectile motion
Inquiry question: How can models that are used to explain projectile motion be used to analyse and make predictions?
Students:
 analyse the motion of projectiles by resolving the motion into horizontal and vertical components, making the following assumptions:
 a constant vertical acceleration due to gravity
 zero air resistance
 apply the modelling of projectile motion to quantitatively derive the relationships between the following variables:
 initial velocity
 launch angle
 maximum height
 time of flight
 final velocity
 launch height
 horizontal range of the projectile (ACSPH099)
 conduct a practical investigation to collect primary data in order to validate the relationships derived above
 solve problems, create models and make quantitative predications by applying the equations of motion relationships for uniformly accelerated and constant rectilinear motion

 investigate the relationship of Kepler’s Laws of Planetary Motion to the forces acting on, and the total energy of, planets in circular and noncircular orbits using: (ACSPH101)
 derive quantitatively and apply the concepts of gravitational force and gravitational potential energy in radial gravitational fields to a variety of situations, including but not limited to:
 the concept of escape velocity
 total potential energy of a planet or satellite in its orbit
