Forces, acceleration and Newton's Law Flashcards
1
Q
What does air resistance mean
A
a force of friction produced when an object moves through the air
2
Q
What does resultant force mean
A
the single force that could replace all the forces acting on an object, found by adding these together. If all the forces are balanced, the resultant force is zero
3
Q
What does terminal velocity mean
A
the maximum speed of an object, reached when the forces moving the objects are balanced by its frictional forces
4
Q
What is Newton’s first law
A
an object remains in the same state of motion unless a resultant force acts on it
5
Q
What is Newton’s second law
A
an object accelerates in the direction of a resultant force
6
Q
What is Newton’s third law
A
when two objects interact, the forces they exert on each other are equal and opposite
