Mass force acceleration equation
Force (N) = mass (Kg) x acceleration (m/s^2)
Acceleration is proportional to…
Resultant force
Acceleration is inversely proportional to…
Mass
Newton’s first law
An object is stationary or constantly moving forever, unless acted on by an unbalanced force
Newton’s second law
When unbalance forces are acting on an object then the object will accelerate/decelerate
Newton’s third law
If body A Exerts a force on body B, body B will exert an equal and opposite force on body A
Mass gravitational field strength and weight equation
Weight (N) = mass (Kg) x gravitational field strength (N/Kg) (9.81 on earth)
Time speed acceleration equation
Acceleration = speed x time
Acceleration velocity time equation
Acceleration = velocity / time
Acceleration mass resultant force equation
Resultant force = mass x acceleration
Force time taken for change change in momentum equation
Force = change in momentum /
time taken for change
