mechanics- year 1

Question 1

newtons first law of motion

Answer 1

states that an object will remain at rest or continue to move with constant velocity unless an external force is applied to it ie a moving object remains in equilibrium as long as the resultant force on it is zero

Question 2

second law of motion

Answer 2

resultant force acting on a particle is proportional to the product of the mass of the particle and its acceleration F=ma
