What happens to speed if you take twice as long to cover the same distance?
It will divide by two i think Indeed: Speed = Distance/(Time) Speed/2=Distance/(2*Time)
A train travels 20 feet in 15 second At this same speed how many feet will it travel in three seconds?
For this you have to work out the speed speed=distance/time therefore the speed here is 20feet/15seconds = 1.3333333m/s Now you have to work out the distance distance = speed X time the distance traveled in 3 seconds is 1.3333333m/s x 3 = 4 feet
If distance is increased but time remains the same what would happen to your average speed?
The average spped increase
Why is the slop on a distance time graph speed?
When looking at a distance vs. time graph, it shows how far an object is traveling over a certain amount of time which can be written like this: distance per time or distance/time (distance divided by time) If we then put units in for distance (let's say meters) and time (seconds) we get this: meters/seconds which is the same as the units for speed.
What is the Formula for calculating mph and distance?
MPH=distance/time or MPH = (distance x 60) / time It's best to get time in terms of 100 (i.e., 20 mins 20 secs = 20.333 mins) Simple formula for that: minutes + [(seconds x 100)/6000] minutes + [seconds / 60] ( same diff. ) Speed equals miles divided by hours Speed = miles / hours miles = speed x hours hours = speed x miles Where: Speed is mph (miles per hour) Miles are distance traveled Hours are length of time to get there If time less than one hour then divide minutes by 60 to get fraction of an hour.
Is Speed decreases as distance decreases for the same time atrue statement?
Yes.
What happens to a graph of time and distance as speed decreases?
Time is on the x axis and distance is on the y axis. There will be a curve starting at zero (presumably) and going upwards towards the right. The slope of the line at any given x value equals the speed at that point in time. Thus the slope will decrease at the same rate that speed decreases.
If the speed of a wave while the wavelength remains the same what happens to the frequency?
if the speed increases the frequency increases if the speed decrease the frequency decreases
Is it possible for the speed to increase at the same time the velocity decreases?
Velocity being a vector, it is tricky to say that "velocity increases or decreases". Its magnitude might decrease - but its magnitude is, precisely, the speed.
As the mass of an object moving at a given speed decreases its kinetic energy does what?
Decrease, if its velocity is held constant. Because p = mv, a smaller m results in a smaller p if v is the same. decrease
If the mass stays the same and distance decreases does the gravity between two objects decrease or increase?
Increases. The closer they are, the harder the pull.
As the speed of a particle increases does its associated wavelength increase or decrease?
The wavelength of waves travelling with the same speed would decrease if the frequency of the waves increases. This is because, speed of a wave is the product of the distance of the wavelength times the frequency of the wave. The velocity of a wave is usually constant in a given medium.
What happens to the forces of attraction between charged objects and uncharged as the distance between them decreases?
As the distance decreases the attraction increases
How would decreasing the time it takes you to run a a certain distance affect your speed?
It would increase your speed. Speed = distance / time so if you decrease the time whilst keeping the distance the same, distance/time increases.
If the waves speed stays the same what decreases as the frequency increases?
The wavelength decreases.
A collision could occur when the distance decreases and bearing between two vessels does what?
stay the same
If the frequency of a wave decrease but the wavelength remains the same what else decrease in the wave?
The velocity decreases. Its the only way.
