3.5.1: Newtons laws of motion

#3.5.1a

Newton’s three laws of motion

#3.5.1b

linear momentum; $p = mv$ ; vector nature of momentum

#3.5.1c

net force = rate of change of momentum;

$F = \dfrac{Δp}{Δt}$

*Learners are expected to know that $F = ma$ is a special case of this equation. *

#3.5.1d

impulse of a force; impulse = $FΔt$

#3.5.1e

impulse is equal to the area under a force–time graph.

*Learners will also be expected to estimate the area under non-linear graphs. *
