Does a camel accelerate if it changes directions but stays at the same speed?
Yes it does, because acceleration is a unit of speed and direction.
If a person is riding a bike and has not changed either speed or direction is that person accelerating?
No. they must be increasing speed to accelerate.
A situation when you can accelerate but the cars' speed doesn't change?
"Acceleration" means a change of speed or direction. If the direction of your motion changes, then there is acceleration, even if your speed doesn't change.
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.
How can velocity change without changing the speed?
Consider velocity as consisting of a speed, and a direction. If any of the two changes - that is, if either the speed or the direction changes - then the velocity changes.
When does the speed of an object change?
An object's speed changes whenever the rate of change between the distance the object travels and the time it takes to travel that distance changes. Do not confuse speed with velocity; speed is scalar, and velocity is vector. Velocity can change when speed remains constant.
Does the speed of an object change?
An object's speed changes whenever the rate of change between the distance the object travels and the time it takes to travel that distance changes. Do not confuse speed with velocity; speed is scalar, and velocity is vector. Velocity can change when speed remains constant.
Distance equals velocity time the equation sHow is that distance varies as time?
Distance is dependent on time. If there is no time, there is no distance, as distance = velocity * time. As time or speed increases so will distance, therefore, if distance increases, either speed or time must increase. If either speed or time = 0, then distance will equal 0.
What happens to the speed of an object that is accelerating?
The speed may, or may not, change. Acceleration means that the velocity changes; this means that either the speed changes, or the direction.
Does a horizontal line on a distance time graph show constant speed?
No. It shows zero speed. Velocity is distance/unit time. The slope of the line shows change in distance / change in time. Since distance never changes as time changes, the change in distance is zero. Alternatively, the slope of a horizontal line is zero. If zero speed is considered "constant", then yes, it does show constant speed but the speed is zero.
Can the distance traveled still be divided by the time taken to travel the distance if the speed accelerates to travel the distance?
The formula, distance = speed x time, or speed = distance / time, assumes constant speed. If the speed changes, then the formula speed = distance / time will give you the average speed over the time period. To get the instantaneous speed in this case, you must divide distance / time for a very short time interval.
What three changes can each cause an object to accelerate?
Three objects that can cause an object to accelerate is, increasing speed, decreasing speed, & changing direction.-Ms. Stroes/Chibudu's Science Class! :)
