What's the formula for speed?
speed= distance/time or s=d/t
1 of 7
How do you calculate speed from a distance-time graph?
Speed=gradient= vertical (y axis)/ horizontal (x axis)
2 of 7
Whats the formula for acceleration
Acceleration = change in velocity/time taken or v-u= a X t
3 of 7
What's the formula for mass, weight and gravity?
weight= mass X gravitational field strength or W= m X g
4 of 7
What is the gravity on earth?
10 N/kg
5 of 7
How do we find the overall effect of forces?
6 of 7
Any resultant force produces acceleration. What's the formula for it?
Resultant force = mass in kilograms X acceleration or F =ma
