Newtons Laws Of Motion Flashcards
What do we mean by interia
The tendency of an object to remain in a steady state
What does Newton’s first law say
The velocity of an object will only chnage if a resultant force is acting on it
What is the resultant force on a stationary object
Zero
What is the resultant force of an object moving at a steady speed in a straight line
Zero
What will an object experience is the resultant force on it is not zero
Acceleration / change in velocity
What is 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
What is 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
What forces are balanced when an object travels at a steady speed?
Resistive forces =driving force
According to Newton’s second law what’s the acceleration of an object inversely proportional to
Mass
What’s the inertial mass of an object
How difficult it is to chnage an objects velocity
What’s the inertial mass of an object
How difficult it is to chnage an objects velocity
What does Newton’s third law say?
When two objects interact they exert equal and opposite forces on each other
Starting to move, stopping moving slowing down speeding up changing direction all examples of what physical process
Acceleration/ change in velocity.
