Topic 2: Mechanics
0.2 Specification notice:
In order to develop their practical skills, students should be encouraged
to carry out a range of practical experiments related to this topic. Possible
experiments include strobe photography or the use of a video camera to
analyse projectile motion, determine the centre of gravity of an irregular
rod, investigate the conservation of momentum using light gates and air
track.
Mathematical skills that could be developed in this topic include plotting
two variables from experimental data, calculating rate of change from a
graph showing a linear relationship, drawing and using the slope of a
tangent to a curve as a measure of rate of change, distinguishing
between instantaneous rate of change and average rate of change and
identifying uncertainties in measurements, using simple techniques to
determine uncertainty when data are combined, using angles in regular
2D and 3D structures with force diagrams and using sin, cos and tan in
physical problems.
This topic may be studied using applications that relate to mechanics, for
example, sports.
2.9 - be able to use the equations for uniformly accelerated
motion in one dimension (SUVAT)
What are the assumptions we make when Must be constant acceleration and travelling
solving problems using the SUVAT in a straight line?
equations?
What are the 5 SUVAT equations for an ● s=vt-0.5at2
object moving at constant acceleration? ● v=u+at
● s=0.5(u+v)t
● s=ut+0.5at2
● v2=u2+2as
, 2.10 - be able to draw and interpret displacement-time,
velocity-time and acceleration-time graphs
What does a straight line represent on a Constant velocity
displacement-time graph?
What does a curved slope represent on a Acceleration
displacement-time graph?
