What else can I help you with?
What the definitioin of speed?
The definition of speed is the size/magnitude/measure of an object's velocity. Average speed = distance divided by time
What happens if an object covers equal distances in equal periods of time?
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.
What is distance divied by time?
Distance divided by time has the dimensions of speed (magnitude of velocity). The (distance an object travels) divided by (the time it takes to travel that distance) is a definition for the object's average speed.
What does the slope of a distance versus-time graph show about the motion of an object?
the slope show the velocity of the object which show its direction and magnitude.
What does velocity divided by the time interval equal?
It equals an undefined entity. The average acceleration of an object equals the CHANGE in velocity divided by the time interval. The term "change in velocity" is not the same as the term "velocity", "average velocity", or "instantaneous velocity".
What is acceleration and what atr two conditions that can change when an object accelerates?
Acceleration is the rate at which the velocity of an object changes over time. Two conditions that can change when an object accelerates are its speed (magnitude of velocity) and direction of motion.
What is the difference between the velocity and the magnitude of the velocity of an object?
Velocity is a vector quantity that includes both the speed and direction of an object's motion, while magnitude of velocity refers to the speed of the object regardless of direction. So, the magnitude of velocity is the absolute value of the velocity vector without considering its direction.
When is the average velocity is equal to the instantaneous velocity?
Average velocity equals the average speed if (and only if) the motion is in the same direction. If not, the average speed, being the average of the absolute value of the velocity, will be larger.
When is speed equal to the magnitude of velocity?
Speed is equal to the magnitude of velocity when the object is moving in a straight line without changing direction. In other words, if the velocity vector is pointing in the same direction as the motion of the object, then the speed will be equal to the magnitude of the velocity.
Can an object change its direction when the magnitude of its velocity is zero?
No, an object cannot change its direction when the magnitude of its velocity is zero. This is because velocity is a vector quantity that includes both magnitude and direction. If the magnitude of the velocity is zero, it means the object is not moving at all and therefore cannot change direction.
What is the decrease in magnitude velocity?
The decrease in magnitude velocity refers to the reduction in the speed of an object or particle. It indicates the change in the object's velocity moving towards a slower speed.
Is Distance the magnitude of average velocity?
No, distance and average velocity are not the same. Distance is the total amount covered by an object irrespective of direction, while average velocity is the displacement of an object divided by the time taken, taking direction into account.
Rate of change of the velocity of an object?
The change in velocity is just the change in velocity. The RATE of change of velocity - how quickly velocity changes - is usually called "acceleration".
What to things must you specify when describing the velocity of an object?
When describing the velocity of an object, you must specify the speed (magnitude of velocity) and the direction in which the object is moving. Velocity is a vector quantity, meaning it has both magnitude and direction.
Distance is the magnitude of average volicity?
Distance is actually the measure of how far an object has traveled, while velocity is the rate of change of an object's position with respect to time. Average velocity is calculated by dividing the total displacement by the total time taken.
Is numerical ratio of average velocity to average speed always equal?
No, the numerical ratio of average velocity to average speed is not always equal. Average velocity is a vector quantity that includes both magnitude and direction, while average speed is a scalar quantity that only considers magnitude. The ratio will be equal only when the object moves in a straight line.
Can the velocity of an object at an instant of time be greater in magnitude than the average velocity over a time interval containing the instant. Can it be less?
Yes, the velocity of an object at an instant of time can be greater than the average velocity over a time interval containing the instant, especially if the object is changing velocity rapidly. Similarly, it can also be less than the average velocity, especially if the object is reversing direction or slowing down during that time interval.
