- 1ParticleMass, but no size
- 2Rough/SmoothFriction present/not present
- 3LightNo Mass
- 4Rigid bodyMass and Size, does not deform
- 5Elastic/InelasticDeforms/does not deform
- 6PlaneFlat surface (eg, a slope)
- 7Vector quantitiesDisplacement
Velocity
Acceleration
Force - 8Scalar quantitiesDistance (m)
Speed (ms^-1)
(Magnitude of) acceleration (ms^-2)
(Magnitude of) force (N)
mass (kg)
time (s) - 9Displacement-Time graphDisplacement = Height
Velocity = Gradient - 10Velocity-Time graphDisplacement = Area
Velocity = Height
Acceleration = Gradient - 11SUVAT valuess = displacement (m)
u = initial velocity (ms^-1)
v = final velocity (ms^-1)
a = acceleration (ms^-2)
t = time (s) - 12SUVAT equationsv = u+at
v^2 = u^2+2as
s = 1/2(u+v)t
s = ut+1/2at^2
s = vt-1/2at^2 - 13Manipulating vectors[a] + [c] = [a+-c]
[b] - [d] = [b+-d]
k*[a] = [ka]
[b] [kb] - 14Resolving vectorsF = [F cos A]
[F sin A]
A = angle - 15Kinematics in 2 dimensionsIn 1 dimensional problems, direction is given as +ve or -ve
In 2 dimensional problems, direction is defined by the vector - 16EquilibriumA particle in equilibrium has constant velocity (could be at rest), and has a resultant force of 0N acting on it (forces are balanced)
- 17Always true FrictionF<= uR
- 18In motion or limiting frictionF = uR
- 19Newton's second lawF = ma
- 20ProjectilesHorizontal: v constant
Vertical: a = -9.8, SUVAT equations - 21Conservation of momentumm1u+m2u=m1v+m2v
