Q

What are Newton’s laws of linear motion

A
  • Newton’s first law = law of inertia
  • Newton’s second law = law of acceleration

Q

Definitions + equations + unit for speed

A

Defined as rate of change of position

Speed in m/s = distance in (m) / time in (s)

Q

Definition, equation + unit of distance

A

Defined as length of the path a body follows when moving from one position to another.

Distance (m) = speed(m/s) x time (s)

Q

Centre of mass + factors affecting

A
  • point of concentration of mass or point of balance of a body

Factors affecting:
- height of centre of mass
- line of gravity
- area if the base of support
- mass of performer
