What happens when an object speeds up, slows down, or changes direction?

When divided by<span> Δt, </span>(<span>vf - vi</span><span>) is used to determine which characteristic?
</span>Acceleration

<span>What happens when a penny is dropped from a height of 20 meters?
</span>The anwer is The force of gravity causes it to accelerate.

<span>What happens when an object speeds up, slows down, or changes direction?
</span>Acceleration

<span>Speed in a specific direction
</span>The answer is velocity 

A decrease in velocity over time

Deceleration

A car travelling at a constant 50 miles per hour turns left on the interstate.  What is happening here?

the answer is Acceleration because speed is constant, but direction is changing.

When the final velocity is less than the initial velocity, this is

<span>Speed</span>

<span>Whether calculating speed or acceleration, this data is required. The Answer Is Time

Those are the correct answers for the test i hope u passed well i know your gonna pass cause they are the correvt answers please make me brainly

Whenever the motion of an object changes . . . speeding up, or slowing down, 
or changing direction . . . that change is called "acceleration".  Acceleration is produced by force on the object.If there is no force on the object, then there is no acceleration.  That means that 
its motion doesn't change.  The object remains in constant, uniform motion . 
moving with steady speed, in a straight line.  

No force is necessary to keep an object moving, only to change its motion.
