Cambridge Lower Secondary PhysicsStage 8 Forces and energy Checklist

Learning objectives

• 8Pf.01I can calculate speed (speed = distance / time).
• 8Pf.02I can interpret and draw simple distance / time graphs.
• 8Pf.03I can describe how balanced and unbalanced forces affect motion.
• 8Pf.04I can identify and calculate turning forces (moment = force x distance).
• 8Pf.05I can explain that pressure is caused by a force, exerted by a substance, acting on an area (pressure = force / area).
• 8Pf.06I can use particle theory to explain pressures in gases and liquids (qualitatively only).
• 8Pf.07I can describe the diffusion of gases and liquids as substances intermingling because their particles move.
