UNIT

2.1

Mechanic Scalars and vectors

s The addition of vectors by calculation or scale drawing.

Limited to two perpendicular vectors.

The resolution of vectors into two components at right

angles to each other; examples should include the

components of forces along and perpendicular to an

inclined plane

Conditions for equilibrium for two or three coplanar

forces acting at a point; problems may be solved either by

using resolved forces or by using a closed triangle

Moments

Moment of a force about a point defined as force x

perpendicular distance from the point to the line of action

of the force; torque

Couple of a pair of equal and opposite forces defined as

force x perpendicular distance between the lines of action

of the forces

The principle of moments and its applications in simple

balanced situations. Centre of mass; calculations of the

position of the centre of mass of a regular lamina are not

expected

Motion along a straight line

Displacement, speed, velocity and acceleration

Representation by graphical methods of uniform and

non-uniform acceleration; interpretation of velocity-time

and displacement-time graphs for uniform and

non-uniform acceleration; significance of areas and

gradients

Equations for uniform acceleration:

Acceleration due to gravity, g; detailed experimental

methods of measuring g

Terminal speed

Projectile motion

Independence of vertical and horizontal motion; problems

will be solvable from first principles. The memorising of

projectile equations is not required

Newton's laws of motion

Knowledge and application of the three laws of motion in

appropriate situations.
