Question,Answer how do you convert m/s into km/s,Multiply by 3.6 (other way for km/s to m/s) How do you calculate speed,speed=distance/time average speed,total distance/total time how do you calculate gradient,gradient=rise(distnace)/run(time) what is velocity,velocity is a speed and direction what is acceleration,accelertaion is any process where the velocity changes how to calculate accelreation,acceleration=change in speed (in m/s)/time taken (in s) what is a force,"a force is a push, pull or twist" list some contact forces,"- friction - air and water resistance - force from water -force from machines/muscles" list some non-contact forces,"- gravitational forces - electrostatic forces - magnetic forces" what is Newtons third law of motion,for every action (force) in nature there is an equal and opposite reaction. what is force measure in,force is measured in newtons (N) using a force meter what is mass measure in?,mass is measure in kg what is mass,how much matter is in an object what is weight,hiow much force is exerted on an object by gravity what is weight measured in,weight is measured in Newtons (N) how to calculate weight,"weight=mass x gravity (N) (kg) (n/kg)" what is gravity on earth,10 what is magnitude,how large the force is (newtons) what is direction,which way the force is acting what is the law of conservation of energy?,"- energy come in different forms - energy cannot be created or destroyed - energy can be changed into other forms of energy" how to calculate force,force = mass x acceleration what is work measured in,measures in joules (J) or kilojoules (kj) what is energy used for,required to make things move or change what is energy measure in,measure is joules (J) or kilojoules (kj) what is energy active forms,"- heat -kinetic -light -sound -electric - electro magnetic" potential forms of energy,"- chemical potential energy - gravity potential energy - magnetic potential energy - nuclear potential energy - elastic potential energy - mechanical potential energy" what is work,work is amount of energy used to move and object what is power measured in,measured in watts (W) or joules per second (J/s) how do you calculate work,work = force x distance what is power,rate at which work is done
