M - Forces and Newton's Laws of Motion Flashcards
1
Q
how do you find the resultant force?
A
add forces acting in the same direction and subtract forces in opposite directions
2
Q
what is Newton’s first law of motion?
A
an object at rest will stay at rest and an object moving at constant velocity will continue to move at constant velocity unless an unbalanced force acts upon the object
3
Q
what is Newton’s second law of motion?
A
the force needed to accelerate a particle is equal to the product of the mass of the particle and the acceleration produced ( F = ma )
4
Q
what is Newton’s third law?
A
for every action there is an equal and opposite reaction
