2.2 Forces And Newton's First Law Flashcards
1
Q
What is the net/resultant force?
A
The single force whose effect is the same as the combined effect of all the individual forces on the body- found by vector addition.
2
Q
What is Newton’s first law of motion?
A
When the net force on a body is zero the body moves with constant velocity.
3
Q
What is equilibrium?
A
When the net force on a body or system is zero.
4
Q
What is dynamic friction?
A
When a body slides over another body.
5
Q
What is static friction?
A
When a force acts on a body but the body does not move.
6
Q
What is important for the formula for static friction?
A
It is for the largest possible frictional force that can develop between the two bodies.
