what is the relationship between speed, distance and time?
speed = distance/time
1 of 26
what is velocity?
how fast something is going in a given direction
2 of 26
what is the formula for acceleration?
acceleration = change in velocity/time taken
3 of 26
true or false: mass = weight x gravitational field strength, is the correct relationship between mass weight and gravitational field strength?
False
4 of 26
what is the first law of motion?
balanced forces means no change in velocity
5 of 26
what is the formula for work done?
work done = force x distance
6 of 26
true or false: the formula for work done only works if the force is moving in the same direction as the movement?
True
7 of 26
kinetic energy has what formula?
kinetic energy= 1/2 x mass x velocity²
