Mechanics Laws Flashcards
1
Q
What is Newton’s first law of motion?
A
A body continues in a state of rest or of uniform motion in a straight line unless it is acted upon by an external force.
2
Q
What does Newton’s law of gravitation state?
A
Force between two particles is proportional to their masses and inversely proportional to the square of the distance between them.
3
Q
What is Newton’s second law of motion?
A
The rate of change of momentum is equal to force OR force acting on a body is equal to the product of its mass and acceleration.
4
Q
What is Newton’s third law of motion?
A
To every action there is an equal and opposite reaction. The action and reaction act on two different bodies simultaneously.
