Newtons Laws Flashcards
What are newtons 1st law?
Law of inertia.
Define what inertia is.
Inertia is an object’s resistance to change its current state or position. An object’s inertia is proportional to its mass. The heavier the object the greater the inertia.
What does newtons’s law of motion state?
An object will remain at rest unless acted upon by an external force. The object will move in a direction of the force acted upon the object.
What is an example where newtons 1st law of inertia can be demonstrated?
A soccer ball will remain at rest or stationary unless a player strikes it.
What does not Newton’s 3rd law state?
States for every action there will be an equal and opposite reaction. When two objects exert a force upon each other, the forces are opposite in direction and equal in magnitude.
What does Newtons 2nd law state?
States that the acceleration of an object is proportional to the force acting upon it and is indirectly proportional to its mass. The greater the force applied to the object the greater the acceleration.
What happens if the mass of an object is reduced?
Less force is required to attain similar acceleration.
What happens in terms of the direction of acceleration?
The acceleration will act in the same direction as the force and will be conserved unless another force acts upon it.
What is the equation for Newton’s 2nd law?
Force = mass acceleration.
What are 2 ways you can increase momentum?
- Increase the mass.
- Increase the velocity of the object.
What happens if an object possesses more momentum?
More force is required to be applied to either stop or slow down the object.
