Speed
➢ =distance / time
Velocity
➢ Is a vector and therefore has both direction and magnitude.
=displacement / time
Accelaration
➢ =(v-u)/t
Where v is initial velocity and u is final velocity
Displacement time graph
upward slope - constant positive velocity
flat line - stationary
,downward slope - negative constant velocity
It can often be easier to just draw a distance-time graph.
velocity-time graph
Acceleration-time graph
➢ a graph describing motion of an object, with acceleration on the vertical axis and
time on the horizontal axis.
upward slope - increasing acceleration
flat line - constant acceleration
downward slope - decreasing acceleration
Adding vectors
➢ Draw both vectors next to each other head to tail and then use Pythagoras and/or
trig to calculate the missing side of the triangle and the angle.
Remember, in order to draw these correctly, you'll probably have to move one of the
vectors.
Moments
, ➢ the turning, movement of a force.
=force x perpendicular distance from the pivot.
Principle of moments
➢ For an object that is in equilibrium:
- the sum of the clockwise moments = the sum of the anticlockwise moments
- There is no resultant force.
Centre of gravity
The point where the entire weight of an object appears to act.
This is essentially the same thing as the centre of mass
This always lies along the line of symmetry. for a flat irregular object hang it from different
points and draw a line straight down. Where the lines connect that's the centre of mass,
because it will always hang directly under a point of suspension.
For other irregular objects it can be found using moments.
Newton's First Law
, ➢ An object at rest stays at rest and an object in motion stays in motion with the same
speed and in the same direction unless acted upon by an unbalanced force.
Newton's Second Law
➢ F=ma
Newton's Third Law
➢ For every action there is an equal and opposite reaction
Kinematics
➢ s = displacement
u = initial velocity
v = final velocity
a = acceleration
t = time.
All of the equations apart from s = (u+v)/2 xt are given in the formula book. Just use
them.
