What else can I help you with?
Can you site an example in which the acceleration of a body is opposite in direction to its velocity?
When an object is thrown upwards, the acceleration due to gravity pulls it downwards, opposite in direction to its initial velocity. This causes the object to eventually come to a stop and reverse its direction as it falls back down.
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.
Why is velocity tangential to the path of a body?
Velocity is a vector; having direction. So, when changing direction constatly to have velocity a tangent can be drawn to the constantly changing path of the object having velocity.
What does Velocity indicate in motion?
rate of change of displacement is known as velocity it shows that how fast or slow a body is moving and in which direction it is moving.
Can a speed of a body be negative?
The 'speed' of a body cannot be negative. But if you are stating the 'velocity' then it can be negative. Negative velocity means it is going opposite to the direction that you decided to call the positive direction.
What is the rate of displacement of a body called?
The rate of displacement of a body is called its velocity.
When is velocity parallel to acceleration?
Velocity is parallel to acceleration when an object is moving with constant speed in a straight line, as the direction of the velocity and acceleration vectors are aligned. This means that the object's speed may be constant, but its direction can change.
What is the differnce between velocity and speed?
Velocity is a vector quantity. So direction is important But speed is a scalar. Body moving around a circle may go with uniform speed but not with uniform velocity as direction is changing continuously
What is the effect of gravity on velocity?
Gravity affects velocity by changing the acceleration of an object. As an object falls, gravity accelerates it, increasing its velocity. Without gravity, an object would move at a constant velocity.
Can a body have zero velocity and still be accelerating?
Yes, a body can have zero velocity and still be accelerating if its speed is changing, either increasing or decreasing, over time. This is because acceleration is a measure of how the velocity of an object is changing, regardless of its current velocity.
What happens to the velocity of a moving body if you change the direction in which the body is moving?
It depends how you changed the direction of the body. If the body is hit by an external force in the direction of motion, the velocity should increase. If the body is hit by an external force in the opposite direction of motion, velocity will decrease.
What is meant by average velocity of a body moving in a particular direction?
The average velocity of a body moving in a particular direction is the total displacement of the body divided by the total time taken to cover that displacement. It gives an overall sense of the object's movement in a specific direction over a period of time.
