Why an object moving in a circular path at a constant speed is undergoing acceleration and has a force excert on it?
-- An object with no net force on it continues moving at constant speed in a straight line.If it's not moving in a straight line, then there must be net force acting on it.-- "Acceleration" is the word for the situation where either speed or direction of motion changes.Even if speed is constant, acceleration is present if the direction is changing.
Describe a situation in which an object accelerates without changing speed?
Acceleration is the rate of change of velocity over time, so velocity must always be changing if the object is accelerating. HOWEVER, you said speed which means only magnitude, not direction. If you stay the same speed, but change direction then you are accelerating. Simple answer: when you are going the same speed in a circle - velocity changes, therefore acceleration changes.
Can an object have constant velocity and but variable speed?
No. Velocity has two parts, speed and direction A constant velocity means that both the speed and the direction must be constant. So a constant velocity must have a constant speed.
When you travel do you always move at a constant speed?
Of course not. Just to begin travel, speed must increase from zero to something, and in order to end travel, speed must decrease from something to zero.
How can you use the word speed up in a sentence?
put it in middle like you must speed up or can you speed up please
Which boat must maintain course and speed when two boats are operating near each other?
When two power driven vessels are meeting or crossing, the vessel that is to the starboard (right) is the stand on vessel. The stand-on (privileged) is to maintain course and speed. Please refer to the link below on the "Stand on" vessel.
A net force must be applied to an object to do everything except?
Maintain a constant speed
When vessels meet the vessel that must maintain course and speed is referred to as?
a wave hits it

What is the speed limit when you come 100 feet of a rail road crossing and you cannot see the tracks for 400 feet in both directions?
The speed limit is 15 MPH when a person comes with in 100 feet of a railroad crossing and can not see the tracks for 400 feet in both directions. If there is a flag person at a railroad crossing the car must stop 15 to 50 feet from railroad.
