Importent Equations

Question 1

S = D/t

Answer 1

Speed (m/s) = Distance (m) / time (s)

Question 2

🔺V = a x t

Answer 2

Change in velocity (m/s) = acceleration (m/s^2) x time (s)

Question 3

M = F x d

Answer 3

Moment (Nm) = Force (N) x perpendicular distance (m)

Question 4

KE = 1/2 x m x v^2

Answer 4

Kinetic energy (J) = 1/2 x mass (kg) x velocity (m/s)

Question 5

GPE = 9.8 x 🔺h x m

Answer 5

Gravitational potential energy (J) = 9.8 (gravity(N)) x 🔺height (m) x mass (kg)

Question 6

F = p x A

Answer 6

Force (N) = pressure (Pa) x area (m^2)

Question 7

energy = mc🔺t

Answer 7

m = mass (kg)

c = (spesific heat capacity) (J/(kg x 0C)

t = temperature change (0C)

Energy (J)
