Year 10 Physics - Motion

the continuous change in the postition of an object in relation to another object which is regarded to be at rest

a branch of physics which studies the motion of objects

a quantity accurately described by a number, with approprtiate units, that has only magnitude

quantities fully described with direction and magnitude

age, time, area, work, distance, speed and mass

force, displacement, velocity and acceleration

a scalar quantity that refers to how much ground an object has covered during it's motion. it has magnitude but no direction.

a vector quantity which refers to how far out of place an object is in consideration of the straight line distance covered and the position of the object from its' original position. has both direction and magnitude.

average soeed (m/s) x time (s)

distance (m) / time (s)

distance (m)/ average speed (m/s)

multiply by 3.6

divide by 3.6

distance - first direction - angle - second direction

use pythagoras (a2 + b2 = c2)

use sine, cosine or tangent rules to find the angle. e.g tan θ = opposite/ adjacent, and then plug in values to find θ and then plug in values to find θ

an angle to an object clockwise from north

with 3 figures e.g 90* = 090* or 230* = 230*

with a protractor

the displacement of an object per a unit of given time. It is a vector quantity, having both direction and magnitude.

v = s/t

s=txv

t=s/v

v = velocity, t = time, s = displacement

speed, unit, direction

the motion of an object (distance and time)

y - axis = distance and x - axis = time

no movement

higher speed

gradual accelaration

the object travels closer towards it's starting position

steady speed

distance/time
