Topic 4 - Laws of motion + momentum Flashcards
1
Q
What is Newton’s first law of motion
A
An object will remain at rest or move at constant velocity unless acted upon by a net force
2
Q
What is Newton’s second law of motion
A
The rate of change of momentum of an object is directly proportional to the resultant force acting upon it and change in momentum is in the same direction as the force
3
Q
What is newton’a third law third law of motion
A
When body A exerts a force on body B body B exerts an equal and opposite force on body A
4
Q
What is the principle of conservation of momentum
A
It states that momentum before collision is equal to the momentum after colliding
