Formulas

Question 1

What are the units for Newton’s Second Law?

Answer 1

Force (in N) = mass (in kg) x acceleration (in m/s^2)

Question 2

What are the units for calculating weight?

Answer 2

Weight (in N) = mass (in kg) x gravitational field strength (in N/kg)

Question 3

What are the units for calculating speed and distance?

Answer 3

Speed (in m/s^-1) = distance (in meters)/time (in seconds)

Distance (m/s^2) = speed (in m/s^-1) x time (in seconds)

Question 4

How do you calculate the speed of an object by finding the slope?

Answer 4

Speed = distance/time -> rise/run -> slope

= y^2 - y^1 / x^2 - x^1
