Motion 2 Flashcards
1
Q
What is friction
A
The force that. Acts when he surface slides/moves over another it always opposes the motion
2
Q
What is Newton’s first law
A
In the absence of a resultant force an object will remain at rest or continue to make at constant velocity
3
Q
What is Newton’s second law
A
The acceleration of an object is directly proportional to the resultant force acting on it
4
Q
Wha5 is Newton’s third law
A
If body a exerts force on body b there is and equal and opposite force exerted on a by b
5
Q
If man is pushing 500n forwards how much weight is c9ming back on him
A
500N
6
Q
How to calculate force in N
A
F=M x A (mass x acceleration)
7
Q
If 3kg car is getting pushed with a force of 6n what is the acceleration
A
A=f/m so 6/3=2m/s
