Forces and
Motion
- Speed
- s=d/t
- Speed=distance/time
- Units
- Speed m/s
- Distance m
- Time s
- Amount of time taken for
an object to cover a
distance
- How fast it is going
- Weight
- w=mg
- Weight=mass x gravity
- It is measured in Newtons (N)
- It is the force of an object due
to mass and the amount of
gravity
- Force
- f=ma
- Force=mass x acceleration
- Terminal Velocity
- Terminal Velocity
is when an object
falls at a constant
velocity in a fluid as
the forces acting on
it are equal
- Work Done
- w=fd
- Work= force x distance
- The units are Joules (J)
- Work done calcuates how
much enegry is needed to
push an object with a
force, a distance
- Newtons Laws
- First Law
- An object will continue
to be either stationary
or move in a straight
line at constant speed,
unless resultant force
acting on it
- Second Law
- Force on object directly
proportional to its mass
times acceleration f=ma
- Third Law
- Every force applied to
object surface there is
opposite equal reaction
