Mechanics Chapter 10 Flashcards
1
Q
What is Newton’s first law of motion?
A
An object at rest will stay at rest or an object moving with constant velocity will retain this velocity unless an unbalanced force acts on the object
2
Q
What does a resultant force on an object cause?
A
Acceleration in the same direction as the resultant force
3
Q
How is the resultant of two or more forces given as vectors calculated?
A
The sum of these vectors
4
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
5
Q
How are problems involving vector forces solved?
A
Use F = ma where F and a are vectors
6
Q
What is Newton’s third law?
A
For every action there is an equal and opposite reaction
