Newtons Laws Flashcards
Define the term in Inertia
The tendency of an object to remain in a steady state at rest or in uniform motion
State Newton’s First Law
The velocity of an object will only change if a resultant force is acting on it
State the resultant force on a stationary object
Zero
State the resultant force on an object moving at a steady speed in a straight line
Zero
Describe what an object will experience if the resultant force on the object is not zero
Acceleration or a change in velocity
State the name of the tendency of an object to remain in a steady state at rest or moving in a straight line at a constant speed
Inertia
Describe what forces are balanced when an object travels at a steady speed
Resistive forces are equal and opposite to the driving Force
According to Newton’s second law state what the acceleration of an object is proportional to
The force acting on it
According to Newton’s second law state what the acceleration of an object is inversely proportional to
Mass
Define the term inertial mass
How difficult it is to change an object’s velocity
Define Newton’s Third Law
When two objects interact they exert equal and opposite forces on each other
Starting to move, stopping moving, speeding up, slowing down and changing directions are all examples of which physical process
Acceleration or a change in velocity
