Mechanics Flashcards
1
Q
What is Newton’s first law of motion?
A
An object will remain at rest or continue to move with constant velocity unless acted upon by a resultant force.
2
Q
What is Newton’s second law?
A
The resultant force acting on an object is directly proportional to the rate of change of its momentum.
3
Q
Which of Newton’s laws is this?

A
Newton’s first law
4
Q
What is an impulse?
A
An impulse of a force is defined as the product of force and the time for which this force acts on an object.(impulse of a force = change in momentum)
