A runner rounding a curve on a track at a constant speed is an example of what type of acceleration?
if an object moves in the same direction and at a constant speed for 4 hours, which of the following is true? a. the object's speed changed during the 4 hours b. the object's velocity did not change. c. the object accelerated during the 4 hours. d. the object decelerated during the 4 hours.<-------- the answer to this is b
Is it true or false that velocity only describes the direction in which the object is moving?
Technically, the term velocity means how fast and in what direction is a given object moving; knowing the velocity is certainly part of calculating how long it takes to get from one place to another, but you also have to know how far apart those places are. If two locations are 100 miles apart, and you can drive that distance at 50 miles per hour, then the trip takes two hours.
What velocity vector will move you 200 miles east in 4 hours traveling at a constant speed?
Positive velocity will move you 200 miles east in 4 hours traveling at a constant speed.
How do you find constant speed?
You didn't specify what data is given. In general, for constant speed, the following formula is important (just use the definition of speed): speed = distance / time; or distance = speed x time. If distance is in km and time in hours, speed will be in km/hour; if distance is in meters and time in seconds, speed will be in meters/second.
How is mass related to motion?
If you take distance to mean displacement, which is the the absolute distance between an original point and another point in a Cartesian coordinate system, then velocity is the displacement of some object divided by the time interval while the object is being displaced.

If driving at a constant speed of 65 miles per hour how far will you travel in 3.5 hours?
227.5 miles
How much work is done if you hold a 50lbs box for 5 hours?
No work is being done. Work is when an object moves in the same direction as the force applied to it.
