AS Mechanics: 10 Forces and Motion Flashcards
1
Q
What is newton’s first law?
A
An object at rest will stay at rest and an object moving with constant velocity will continue to mice who a constant velocity unless an unbalanced force acts on the object.
2
Q
How can you find the resultant of two or more forces given as vectors?
A
By adding the vectors.
3
Q
What is newton’s first law?
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
How can you solve problems involving connected particles?
A
By considering the particles separately or, if they are moving in the same straight line, as a single particle.
5
Q
What is the relation between tension on both sides of a pully?
A
They are equal.
