What does the solid line on this graph represent?
Constant speed
Acceleration
At rest
deceleration
What is the line on this graph showing?
moving away from starting point at a constant speed
moving back towards the starting point at a constant speed
acceleration (getting faster)
deceleration (getting slower)
An object at rest will remain at rest unless acted upon by an unbalanced force. Likewise an object in motion will remain in motion unless acted upon by an unbalanced force.
Newton's 2nd law
Newton's 3rd law
Fig Newton's law
Newton's 1st law
how are acceleration and velocity related?
acceleration is the rate of change of velocity in time.
time is the rate of change in velocity in acceleration.
they are not related.
they are the same thing.
how does mass affect acceleration?
when one grows, the other shrinks, inversely
directly proportional
it doesn't affect it.
mass will always make the acceleration faster.
