acceleration air resistance average speed how much the speed increases each second the frictional force which makes it difficult for a vehicle to move through air 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
Beath High School - Int 1 Physics 2

force a push, pull or twist which causes an object to speed up or slow down.
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

light gate to metres per second squared (m/s 2 ) light gate lubrication mass a lamp and a light sensor; used to measure speed making surfaces more slippery to reduce friction a measure of the amount of substance in an object metres per second (m/s) the units of speed metres per second squared (m/s 2 ) the units of acceleration

newton the units of force newton balance apparatus for measuring forces range the horizontal distance travelled by a projectile rebound skydiver 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

speedometer spoiler the instrument in a vehicle to measure its instantaneous speed a type of ‘wing’ on a car to make it more steamlined streamlined shaped to cut through the air (or water) more easily streamlining shaping an object to make it cut through the air (or water) more easily terminal velocity the fastest speed an object reaches as it falls through a fluid

weight wind tunnel 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
