FORCES Flashcards
What is mass and weight
mass is the amount of matter a object has weight is mass multiplied by acceleration
equation of force
f= mass * acceleration
dose mass change
no
state newtons 3 laws
Newton’s First Law of Motion states that an object at rest or moving at a constant speed, will continue to be at rest or moving at a constant speed UNLESS acted upon by an unbalanced force.
Newton’s Second Law states that the acceleration of an object is directly proportional to the force applied to that object; which also means that the greater the mass of an object, the greater its weight.
His third law states that for every action (force) in nature there is an equal and opposite reaction.
how to find centripetal force
f= m*v^2 / r
hooks law equation
F = kx
F is the tension force; x is the extension and
k is the spring constant.
why object is accelerating even
though its speed is constant.
velocity is a vector as it has both magnitude
and direction.
Acceleration is a change in velocity, which could be either a change in speed or direction
what is the law of moments
