Title: Intermediate 1 Physics

1
Intermediate 1 Physics
• Movement Glossary
• acceleration to collision
• force to kilogram
• light gate to m/s2
• newton to skydiver
• speedometer to terminal velocity
• weight to wind tunnel

2
acceleration to collision
• acceleration

how much the speed increases each second
the frictional force which makes it difficult for
a vehicle to move through air
air resistance
average speed
total distance divided by time
balanced forces
equal and opposite forces acting on the same
object
collision
this is when two objects hit each other and
affect each others motion
3
force to kilogram
a push, pull or twist which causes an object to
speed up or slow down.
• force

friction
a force which opposes motion
gravity
the attraction which a planet exerts on any
object near it
instantaneous speed
how fast something is moving at a moment in time
kilogram
the unit of mass
4
light gate to metres per second squared (m/s2)
• light gate

a lamp and a light sensor used to measure speed
making surfaces more slippery to reduce friction
lubrication
mass
a measure of the amount of substance in an object
metres per second (m/s)
the units of speed
metres per second squared (m/s2)
the units of acceleration
5
newton to skydiver
• newton

the units of force
newton balance
apparatus for measuring forces
range
the horizontal distance travelled by a projectile
rebound
an object, like a ball, bouncing off a surface
a person who falls freely through the air from a
plane for a while before opening a parachute
skydiver
6
speedometer to terminal velocity
the instrument in a vehicle to measure its
instantaneous speed
• speedometer

a type of wing on a car to make it
more steamlined
spoiler
shaped to cut through the air (or water) more
easily
streamlined
shaping an object to make it cut through the air
(or water) more easily
streamlining
terminal velocity
the fastest speed an object reaches as it falls
through a fluid
7
weight to wind tunnel
• weight

the force of attraction a planet exerts on an
object
a place where air can be blown over a vehicle to
check how streamlined it is
wind tunnel
