Students learn to:
Students:
1. The Earth has a gravitational field that exerts a force on objects both on it and around it define weight as the force on an object due to a gravitational field perform an investigation and gather information to determine a value for acceleration due to gravity using pendulum motion or computer-assisted technology and identify reason for possible variations from the value 9.8 ms-2 gather secondary information to predict the value of acceleration due to gravity on other planets analyse information using the expression:
to determine the weight force for a body on Earth and for the same body on other planets
explain that a change in gravitational potential energy is related to work done
define gravitational potential energy as the work done to move an object from a very large distance away to a point in a gravitational field
Students learn to:
Students:
2. Many factors have to be taken into account to achieve a successful rocket launch, maintain a stable orbit and return to Earth describe the trajectory of an object undergoing projectile motion within the Earth’s gravitational field in terms of horizontal and vertical components solve problems and analyse information to calculate the actual velocity of a projectile from its horizontal and vertical components using :
perform a first-hand investigation, gather information and analyse data to calculate initial and final velocity, maximum height reached, range and time of flight of a projectile for a range of situations by using simulations, data loggers and computer analysis identify data sources, gather, analyse and present information on the contribution of one of the following to the development of space exploration: Tsiolkovsky, Oberth, Goddard, Esnault-Pelterie, O’Neill or von Braun solve problems and analyse information to calculate the centripetal force acting on a satellite undergoing uniform circular motion about
