Force and Motion
Procedural Knowledge: what I should be able to do
a definition for force and the SI units for force
that a force can be contact or non-contact
some types of forces:
weight, thrust, friction, resistance, tension
that forces can be balanced and unbalanced
the definition of “scalar” and “vector” and which
motion quantities are scalar or vector quantities
the difference between distance and displacement
interpret given situations and state distance travelled
and displacement
SI units for distance and displacement
the difference between speed and velocity
convert km/h to m/s and m/s to km/h
formulae for average speed and average velocity
SI units for speed and velocity
definition for acceleration and deceleration and
difference between acceleration and deceleration
formula for acceleration
SI units for acceleration
describe why there is acceleration due to gravity
and recall that g = 9.8m/s2 downwards
interpret given situations and calculate average speed
and average velocity
interpret ticker-timer tapes to recognise state of motion:
constant velocity, acceleration, deceleration
use a ticker-timer to gather data to determine speed and
acceleration of an object in straight line motion
use motion sensors to gather data to determine speed
and acceleration of objects moving in a straight line
interpret given situations and calculate acceleration or
deceleration
state Newton’s Laws of Motion – 1st, 2nd and 3rd
solve vertical motion problems
the effect of balanced and unbalanced forces on the
motion of an object (N1L)
that inertia is the resistance of an object to change
in motion (N1L)
the meaning of the terms mass, weight, inertia and
momentum
recognise which of Newton’s Laws of Motion apply to
various practical situations
identify forces acting on objects that are stationary or
moving in a straight line
formulae for weight and momentum
SI units for mass, weight and momentum
that weight varies according to the position of an
object relative to the earth (or other large mass!)
formula for N2L:
F=ma
solve problems involving N2L: F=ma
that every force has an equal and opposite reaction
force (N3L)
recall and use “extension” motion formulae
how gradient of disp-time graphs and
velocity-time graphs describe motion
rearrange formulae to make a different variable the
subject of the formula: average speed and velocity,
acceleration, F=ma, extension motion formulae.
apply and use extended motion and other formulae to
calculate aspects of an object’s motion
interpret motion graphs – displacement-time and
velocity-time to find average velocity and acceleration
Extending and Refining Knowledge: what can I do to show my understanding?
o Comparing
o Classifying
Contact and non-contact forces.
Balanced and unbalanced forces.
Mass and weight.
Inertia and momentum.
Forces as contact or non-contact.
Forces as balanced or unbalanced.
Motion as uniform or non-uniform.
