### If the speed of an object changes from 121 ms to 98 ms during a time interval of 12s what is the acceleration of the object?

Average acceleration during the time interval = (change on speed) / (time for the change) =(98 - 121) / (12) = -23/12 = negative (1 and 11/12) meters per second2

B -1.92 m/s2

### What are three components needed to find an object acceleration?

Using the definition of acceleration as change of speed / time, you basically need to know: * A time interval during which the object accelerates. * The velocity at the beginning of this time interval. * The velocity at the end of this time interval.

### What changes as an object moves with a constant acceleration?

During constant acceleration, either the object's speed changes at a constant rate, or the direction of its motion changes at a constant rate, or both.

### What is the formula to determine the acceleration of an object moving in a strait line?

Acceleration = (speed at the end of some time interval minus speed at the beginning of the interval)/(length of the time interval)

### If the speed of an object changes from 121ms to 98 ms during a time interval of 12s what is the acceleration of the object?

Acceleration is equal to the change in velocity over the change in time [a=(vf-vi)/(tf-ti). a=(98m/s - 121 m/s)/(12s)=(-23m/s)/(12s)=-1.92m/s^2

### Is acceleration how quickly an object's velocity changes?

Yes, acceleration is the how the velocity changes. This also includes when an object turns

Acceleration

### If the speed of an object changes from 121ms to 98ms during a time interval of 12 s what is the acceleration of the object?

We have this equation: Velocity after = Initial velocity + (acceleration * time) So, let's plug in the numbers into this equation. 98m/s = 121m/s + (acceleration * 12seconds) So, -23 = 12 seconds * acceleration dividing 12 from both sides, the acc. is -1.92m/s/s. (Yes, those are the UNITs of acceleration. And it's negative because the object slows down. )

### Why at a constant speed if an object changes its direction it is considered to be acceleration?

Acceleration is a direction plus a speed. If either changes then the acceleration changes.
