Newtons Laws Of Motion Flashcards
What is an object that is not moving?
At rest
What is Newton’s first law of motion?
An object at rest remains at rest and an object in morn stays in motion at a constant speed and in a straight line unless acted on by an unbalanced force.
When will objects stop moving?
When a push or pull is exerted on them.
What will happen to moving objects?
They will keep moving forever unless an unbalanced force acts on them.
What unbalanced force acts on objects to make them stop moving?
Friction
What is inertia?
An objects tendency to resist a change in motion.
Inertia is the reason a moving object…..
keeps moving at the same velocity unless a force changes it’s speed or direction
Mass is…
A measure of inertia in an object
What is Newton’s second law?
The acceleration of an object depends on the mass of the object and the amount of force applied.
What happens when the acceleration of an object decreases/ increases?
The acceleration of an object decreases as it’s mass increases and it’s acceleration decreases as mass increases.
What happens to the force as the acceleration increases?
The force increases.
What is the formula for acceleration?
A=F/M
What is the formula for force?
F= A* M
What is Newton’s third law?
Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first.
All forces act in….
Pairs
