B.2.1.1—Linear and angular motion can be analysed using Newton’s laws of motion.
The motion of an object can be described using speed, velocity and acceleration.
The resultant motion of an object is determined by the sum of the forces acting on it.
The following principles relate to applications of Newton’s laws.
Stability—factors affecting stability include the height of the centre of mass relative to the supporting surface, the size of the support base, the position of the line of gravity relative to the support base and the mass.
The principle of summing joint forces.
Linear motion—the greater the impulse applied, the greater the change in momentum.
The principle of impulse direction.
Angular motion—this is produced by the application of a force acting at a distance from the centre of mass: an eccentric force.
Angular momentum is conserved when an athlete or object is free of additional eccentric forces.
The equations for speed, linear velocity, angular velocity, acceleration and linear momentum are found in the SEHS data booklet.
The equation for force and weight is found in the SEHS data booklet.
The use of trigonometry is not assessed. Calculations are limited to three terms for SL and to four terms for HL.

B.2.1.2—A collision results in a change in momentum in the colliding bodies.
The change in momentum is equal to the impulse applied to the object.
Collisions involving a ball are affected by its coefficient of restitution.
The equation of coefficient of restitution is found in the SEHS data booklet.
Calculations in assessment will be limited to one dimension.
B.2.1.3—The force of friction is determined by the coefficient of friction.
The coefficients of static and dynamic friction depend on the materials in contact.
Frictional force can be modified to improve sports performance.
Equations for the coefficients of static and dynamic friction are found in the SEHS data booklet.
B.2.1.4—Work results from the application of a force over a distance.
When work is done, energy is transformed from one form to others.
Power is a measure of the rate at which work is done. Measuring power output can therefore be a measure of work intensity.
Power output can be optimized through correct technique and the effective design of sports equipment.
Equations for work and power are found in the SEHS data booklet.
