Newton's Second Law Flashcards
What does Newton’s second law state?
When a resultant force acts on a mass then there will be a change in its velocity
What does the resultant force determine?
The size and direction of the subsequent acceleration of the mass
What is the force called that can replace two or more forces acting on an object?
Resultant force
How do you find the resultant force of two or more forces acting on the same straight line or are parallel?
Add them together
Acceleration is the same direction as….
The force
If the resultant force is 0, what is the acceleration?
0
What does a negative force mean?
The object is accelerating backwards/slowing down.
What is the inertial mass?
A measure of how difficult it is to change the velocity of a moving object
How do you calculate acceleration?
Force / mass
How do you calculate the force?
Mass X acceleration
