Newton's Laws Flashcards
What is Newton’s first Law?
An object will remain at rest or remain at constant velocity, unless it is acted upon by an external force
What is Newton’s second Law?
The net force acting on an object is equal to the rate of change of linear momentum of the object. The net force and change in momentum are in the same direction
What is Newtons third Law?
When two bodies interact, the forces they exert on each other are equal and opposite
What is impulse of a force?
The rate of change of momentum
Which part of a force against time graph shows impulse?
The area under the graph
What is a special case of Newton’s second law where mass remains constant?
F=ma
The two forces cause by Newton’s 3rd law must…
Act on different bodies
Are equal in magnitude
Are opposite in direction
Are of the same type
What unit does impulse have?
Ns or kgms-1
