What are the two things needed for velocity?
Since, velocity is a vector quantity, it has two components to it. The magnitude, which is the speed, and the direction in which the motion is happening.
What 2 things does a person need to know to determine the velocity of an object?
One must include direction information in order to fully describe the velocity of the object. For instance, you must describe an object’s velocity as being 55 mi/hr, east. This is one of the essential differences between speed and velocity.
What are the main features of a velocity in a uniform motion?
To summarize, an object moving in uniform circular motion is moving around the perimeter of the circle with a constant speed. While the speed of the object is constant, its velocity is changing. Velocity, being a vector, has a constant magnitude but a changing direction.
What is the relationship between the position and velocity vectors for motion on a circle?
The position and velocity vectors are always tangent to the acceleration vector.
Can give examples for uniform motion?
Examples of Uniform Motions. A car going along a straight level road at steady speed. A ship steaming on a straight course at steady speed. A train going along the tracks at steady speed. Earth moving round the sun is a uniform motion.
What is uniform motion explain with example?
If an object is travelling with uniform motion, it is moving in a straight line at a constant speed. For example, when a car travels at a constant speed, the driving force from the engine is balanced by the resistive forces such as air resistance and frictional forces in the car’s moving parts.
What is uniform motion in short answer?
Definition: This type of motion is defined as the motion of an object in which the object travels in a straight line and its velocity remains constant along that line as it covers equal distances in equal intervals of time, irrespective of the duration of the time.
Which of the following is the example of a uniform circular motion?
Uniform circular motion is a specific type of motion in which an object travels in a circle with a constant speed. For example, any point on a propeller spinning at a constant rate is executing uniform circular motion. Other examples are the second, minute, and hour hands of a watch.
What is the motion and time?
Motion is the change in the position of an object with respect to its surroundings. It is the distance moved by an object or its displacement. The distance moved by an object in a unit time is called its speed. The speed of an object helps to compare whether a body is moving fast or slow.
What is called Speed?
Speed is the distance of a moving object in a given amount of time. Speed is a measure of how fast something is moving. The average speed of an object in a certain time is the distance the object travelled divided by the time.
What is meant by slow and fast motion?
If a body or a particle moves with more speed, the motion is said to be fast motion and if a body or a particle moves with less speed, the motion is said to be slow motion. The object that shows fast motion is said to have a higher speed while the one with slow motion is said to have a slow speed.
