When an object travels covers equal distances in equal amount of time it can be said that it is traveling with constant speed. speed = distance/time. Unit of speed is m/sec. speed is a scalar quantity.
To find the volume of an irregular object such as a rock, you have to use displacement. If you place the object in a graduated cylinder filled with water, the volume of the object is equal to the amount of water that the object displaces. For example, if a graduated cylinder is filled with 100mL of water, and you place an object such as a rock and the water rises from 100mL to 106mL, then the volume of the rock is 6.
The bouyant force on an object is equal to the weight of the fluid the object displaces.
If the density of an object which is equal to one(Which is also the density of the water), the object will neither sink nor float but it will be unstable, sometimes you will see the object sink then float. In other words the object is unstable in water....XD
Work = force x distance. If distance = 0, work = 0 because force x 0 = 0.
effort, resistance
When an object travels covers equal distances in equal amount of time it can be said that it is traveling with constant speed. speed = distance/time. Unit of speed is m/sec. speed is a scalar quantity.
The object is moving at a constant speed.
In that case, the object is said to move at constant speed.
Then you can say that the object's speed and the magnitude of its velocity are constant, and the magnitude of its acceleration is zero.
It is called uniform motion because the object covers equal distances in equal intervals of time which is why it has a constant velocity.
Constant speed means that an object is moving at a consistent rate without any change in its velocity over time. This means that the object covers equal distances in equal intervals of time.
Uniform motion.
-- The distance/time graph for an object in uniform motion is a straight line,which may be sloped.-- The distance/time graph for an object in non-uniform motion may be a linethat isn't straight. But even if the graph is a straight line, that's not enoughto guarantee that the object's motion is uniform ... the distance/time graphreveals the object's speed, but not the direction of its motion.
A distance-time graph is a straight line when the object is moving at a constant speed. This means that the object covers equal distances in equal time intervals. It indicates a uniform motion without acceleration or deceleration.
An object is said to have uniform velocity when it is moving in a straight line and covers equal distances in equal time intervals. This means the object's speed remains constant and there is no change in its direction of motion.
An object is traveling in uniform motion when it covers equal distances in equal time intervals and its velocity remains constant. This means the object is moving in a straight line at a consistent speed without changing direction.
Uniform motion is when an object travels in a straight line at a constant speed. This means that the object covers equal distances in equal intervals of time. There is no change in direction or acceleration during uniform motion.
