1.6- Newtoms Laws Of Motion Flashcards
1
Q
State Newton’s first law
A
A body at rest will remain at rest unless a resultant force acts on an object. If a body is at a constant speed in a straight line it will continue until a resultant force acts on it
2
Q
State Newton’s second law
A
The acceleration of an object in inversely proportional to its mass/ directly proportional to the resultant force on it and takes place in the same direction as the unbalanced force
3
Q
Definition of the newton
A
The force needed to cause a mass of 1kg to have an acceleration of 1ms^-2
4
Q
State Newton’s third law
A
If body A exerts a force on body B then body B exerts a force of the same size on body A in the opposite direction
