Question 11

Speed equation

Answer 11

speed= Distance / Time → (m/s)

Question 12

Acceleration equation

Answer 12

Acceleration = Change in velocity / Time → (m/s²)

Question 13

Force euqation

Answer 13

Force = Mass × Acceleration → (N) (1 Newton = 1 kg·m/s²)

Question 14

WOrk done equation

Answer 14

Work done (Energy) = Force × Distance → (J) (1 Joule = 1 N·m)

Question 15

power equation

Answer 15

Power = Energy / Time → (W) (1 Watt = 1 J/s)

Question 16

Pressure equation

Answer 16

Pressure = Force / Area → (Pa) (1 Pascal = 1 N/m²)
