Answer 1

Answer:

in uniform circular motion velocity of a particle is variable in direction

Explanation:

Answer 2

Answer:

In uniform circular motion velocity of particle is variable in direction

Explanation:

Velocity:

• In uniform circular motion velocity of a particle is variable in direction but constant in magnitude.
• The velocity of a body is the distance travelled per second by the body in a specificed direction.
• If a body travels equal distances in a particular direction, in equal intervals of time, the body is said to be moving with a uniform velocity.
• Thus, the rate of change of displacement of a body with time is called the velocity.
• It is numerically equal to the displacement of the body in one second.
• It is a vector quantity.
• For velocity, both its magnitude and direction must be specified.
• Two bodies are said to be moving with same velocity if both of them move with the same speed in the same direction.
• On the other hand, if two bodies move with the same speed but in different directions or with different speed in the same Direction, they are said to be moving with different velocities.
