Newtons Laws Of Physics Flashcards
What is newtons first law?
An object at rest stays at rest, an object in motion stays n motion: unless acted on by a resultant force.
What is the resultant force of a stationary object?
0N
What is the resultant force of an object witch is moving at a constant speed?
0N
According to the first law, what is needed for objects to do anything? (change direction, Start moving, slow down, Speed up)
Resultant forces.
What is an inertia in relation to newtons first law?
A consequence of newtons first law.
What is inertia?
Tendency for motion to not change.
What is the formula that links resultant force, acceleration and mass?
F = m x a
What type of relationship does force and acceleration has?
Directly proportional
According to inertia, what is more difficult to stop moving, a small object or a large object moving at the same speed?
Large object
What is newtons second law?
F = m x a
What does M in the formula M=F/a represent?
Inertial mass
What is newtons third law?
If objects A applies a force on Object on object B, object B applies an equal and opposite force on object A.
What things are required for a situation to be a newtons third law situation?
- Force must be action of different objects.
- Forces must be equal in side.
- Forces must be in opposite directions
