Newtons 1st law, 2nd law,mass and weight

• Newtons second law is

  resultant force(N)= mass(kg) × acceleration(m/s^2)
• The greater the force the bigger the acceleration or deceleration
• The greater the mass the smaller the acceleration or deceleration
• If resultant force applied to object it accelerates or decelerate
• Inertia is the tendency of objects to stay at rest or in same motion
• Inertia mass is how difficult it is to change velocity of object
• Inertia mass= force/ acceleration
• The bigger the mass the greater its gravitational field strength
• The bigger the gravitational field strength bigger the weight
• Gravity constant is measured by kilogram per second squared
• Newtons first law is an object will remain at rest or will move at constant velocity(straight direction) unless an unbalanced force acts on it
