State Newton’s 1st law of motion.
An object at rest will stay at rest and an object moving at a constant velocity will continue at a constant velocity unless acted on by a resultant force
What is another term for rest?
Static equilibrium
What is meant by inertia?
An object’s reluctance to change motion
What quality of an object is inertia dependent on?
Mass
State Newton’s 2nd law of motion.
The force needed to accelerate an object is equal to the sum of its mass and the acceleration produced
State the equation for the motion of an object according to Newton’s 2nd law.
F = ma
State Newton’s 3rd law of motion.
Every action has an equal and opposite reaction.
What conditions must be met for a Newton’s pair?
They must be of the same type of force
They must act along the same line
What is the relationship between force and momentum?
The force is directly proportional to the rate of change of momentum
