Question

Please type all the formulas used in the chapter Motion and chapter force and laws of motion ​

Answer 1

Speed


where v is speed in metres per second, s is distance in metres, and t is time in seconds

Velocity



where v is velocity in metres per second, d is displacement in metres, and t is time in seconds

Acceleration


where a is acceleration in m/s2, v is change in velocity in metres per second, and t is time in seconds

Weight

W = mg
where W is weight, m is mass in kilograms and g is acceleration due to gravity in m/s2
(on Earth, acceleration due to gravity is approximately 9.8 m/s2)

Force

F = ma
where F is force in newtons, m is mass in kilograms, and a is acceleration in m/s2

Work Done

W = Fs
where W is work in joules, F is force in newtons, and s is the distance over which the force is applied

Gravitational Potential Energy

GPE = mgh where GPE is gravitational potential energy in joules, m is mass in kilograms, g is the acceleration due to gravity in m/s2, and h is height in metres (on Earth, acceleration due to gravity is approximately 9.8 m/s2)

Elastic Potential Energy

EPE =  kx2
where EPE is elastic potential energy in joules, k is the spring constant of the object, and x is the length of extension or compression in metres

Power

P = W
t

we have the the three equations of Motion as

 

1) v= u + at

 

2) s = ut + (1/2)at2

 

3) v2 = u2 + 2as
