What does Newton’s first law of motion say?
A resultant force is required to change the motion of an object
What will happen if the resultant force acting on a stationary object is zero?
The object will remain stationary
What will happen if the resultant force acting on a moving object is zero?
The object will continue moving at the same velocity
What does Newton’s second law of motion say?
A non-zero resultant force will always produce acceleration in the direction of the force
Used as Newton’s second law, what is the equation that links force, mass and acceleration?
In Newton’s second law of motion, what is the relationship between force and acceleration?
The resultant force is directly proportional to the acceleration produced
In Newton’s second law of motion, what is the relationship between acceleration and mass?
Acceleration is inversely proportional to the mass of an object
