What is the speed and direction of a moving body called?
The speed and direction of a moving body is called velocity. Velocity is a vector quantity that specifies both the speed of an object and the direction in which it is moving.
What will be the body said ----- velocities when average and instantaneous velocities are equal?
When the average velocity of a body is equal to its instantaneous velocity, it means that the body is moving at a constant speed in a straight line. This indicates that the body's motion is uniform, with no acceleration or deceleration occurring.
When do the velocity and speed of a moving body become equal?
The velocity and speed of a moving body become equal when the motion is along a straight line with no change in direction. In such cases, the velocity and speed have the same magnitude.
When can you say that a moving body has diccelerated?
A moving body is decelerating when its velocity is decreasing over time. This can be observed when the speed of the body is decreasing, or when the body is moving in the direction opposite to its initial velocity. Deceleration is the opposite of acceleration, where acceleration is the rate of change of velocity, deceleration is the rate at which the speed decreases.
When the speed of the body moving in an straight line changes continuously then the body acquires?
When the speed of a body moving in a straight line changes continuously, the body acquires acceleration. This acceleration could be either positive (speeding up) or negative (slowing down), depending on whether the speed is increasing or decreasing.
Can the average speed of a body be zero and can the average velocity of a moving body be zero?
Since speed is a scalar quantity, the only way the average speed can be zero is if the instantaneous speed is at all times zero, making it not a moving body, so no on the average speed. The average velocity, on the other hand, can easily be zero. The simplest example is you running in a circle.
Can the average speed of a moving body be zero Explain?
Yes, when it comes back to the starting point.
What is the difference between insantaneous speend and average speed?
The instantaneous speed is the speed of a moving body at an instant. Average speed is the overall speed through a period of time. These are two important aspects of differentiation in calculus.
What is the speed and direction of a moving body called?
The speed and direction of a moving body is called velocity. Velocity is a vector quantity that specifies both the speed of an object and the direction in which it is moving.
Can a body have nonzero average speed but have zero average velocity give example?
Yes, a body can have a nonzero average speed but zero average velocity if it moves around a closed path and returns to its starting point. For example, if a car travels around a circular track at a constant speed, its average speed will be nonzero (as distance is covered), but its average velocity over the entire trip will be zero as the displacement is zero.
What happens to the velocity of a moving body if you change the speed at which the body is moving?
The velocity changes. called acceleration.
What will be the body said ----- velocities when average and instantaneous velocities are equal?
When the average velocity of a body is equal to its instantaneous velocity, it means that the body is moving at a constant speed in a straight line. This indicates that the body's motion is uniform, with no acceleration or deceleration occurring.
What would be the shape of a speed time graph of a body moving with variable speed?
If a body is moving with variable speed, then the only thing you can say aboutits speed/time graph is that the graph is not a straight, horizontal line.
How does speed increase the weight of a moving body?
Speed does not increase the weight of a moving body. Weight is determined by the mass of the object and the force of gravity acting on it, and it remains constant regardless of speed. Speed only affects the kinetic energy of the body, which is proportional to the square of the speed.
When do the velocity and speed of a moving body become equal?
The velocity and speed of a moving body become equal when the motion is along a straight line with no change in direction. In such cases, the velocity and speed have the same magnitude.
If net force is zero then the body will move or not?
If the net force on a body is zero, then the body will not accelerate ... its speed and direction of motion won't change. If it was moving a second ago, then it will continue moving at the same speed and in the same direction. If it was not moving a second ago, it won't start moving.
When can you say that a moving body has diccelerated?
A moving body is decelerating when its velocity is decreasing over time. This can be observed when the speed of the body is decreasing, or when the body is moving in the direction opposite to its initial velocity. Deceleration is the opposite of acceleration, where acceleration is the rate of change of velocity, deceleration is the rate at which the speed decreases.
