Law of Conservation of Momentum
Action and reaction forces are equal and opposite, but they are NOT ___ because they act on different objects so they don’t cancel out.
mass
balanced force
unbalanced force
acceleration
___ is a property of a moving object that makes it hard to stop. It equals the object’s mass times its velocity.
Momentum
Velocity
Weight
Inertia
Whenever an action and reaction occur, momentum is transferred from one object to the other. However, total momentum is conserved. This is ___
Newton’s third law of motion
Newton’s first law of motion
Newton’s second law of motion
the Law of Conservation of Momentum
The equation for acceleration can be rewritten as __ to calculate the net force acting on an object when its mass and acceleration are known.
a = F / m
F = m * 9.8 m/s2
1 Newtons (N) = 0.225 pounds (lbs)
p = m * v
The formula for calculating weight is ___, where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms.
a = F / m
F = m * 9.8 m/s2
1 Newtons (N) = 0.225 pounds (lbs)
p = m * v
To calculate the momentum of a moving object, use the equation
a = F / m
F = m * 9.8 m/s2
1 Newtons (N) = 0.225 pounds (lbs)
p = m * v
What is the conversion factor for changing Newton's into pounds
a = F / m
F = m * 9.8 m/s2
1 Newtons (N) = 0.225 pounds (lbs)
p = m * v
