equations of motion Flashcards
1
Q
what is newton’s first law
A
An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force
2
Q
what is newton’s second law
A
the resultant force acting on an object is equal to its mass multiplied by its acceleration, expressed by the equation: F = ma
3
Q
what is newton’s third law
A
for every action, there is an equal and opposite reaction
4
Q
equations of motion
A
v^2 = u^2 - 2aS
acceleration = v-u/t
