If one object has a greater speed than a second object, does the first necessarily have a greater acceleration? Explain, using examples.
Steady Motion: The velocity of the object constant
Accelerated motion: The velocity of the object increases or decreases.
The acceleration shows how fast the velocity of the object increases or decreases.
Acceleration is change in velocity in unit time.
So greater speed doesn’t mean greater acceleration, an object moving at constant speed has zero acceleration. The object starting to move from rest has an acceleration bigger than zero.
