Speed and velocity

Joseph jogs from one end A to other end B of a straight 300m road in 2 minutes 30 seconds and then turns around and jogs 100 m back to point C in another 1 minute. What are Joseph's average speeds and velocities in Jogging (a) from A to B and (b) from A to C ?

Joseph jogs from one end A to the other end B of a straight 300 m road in 2 min 50 s and then turns around and jogs 100 m back to point C in another 1 min. What are Joseph's average speeds and velocities in jogging (i) from A to B and (ii) from A to C ?

A particle is projected from ground with velocity 40 m//s at 60^@ from horizontal. (a) Find the speed when velocity of the particle makes an angle of 37^@ from horizontal. (b) Find the time for the above situation. (C ) Find the vertical height and horizontal distance of the particle from the starting point in the above position. Take g= 10m//s^2 .

Which of the following remains constant in uniform circular motion. Speed or Velocity or both ?

Which quantity, speed or velocity gives the direction of motion of a body?

Assertion : Magnitude of average velocity is equal to average speed, if velocity is constant. Reson : If velocity is constant, then there is no change in the direction of motion.

Which of the following is a null vector (a) velocity vector of a body moving in a circle with a uniform speed (b) velocity vector of a body moving in a straight line with a uniform speed (c) position vector of the origin of the rectangular coordinate system (d) displacement vector of a stationary object

Which of the following properties of a proton can change while it moves freely in a magnetic field? (There may be more than one correct answer). (a) mass (b) speed (c) velocity (d) momentum

Speed vs Velocity

Assertion : Particle A is moving Eastwards and particle B Northwards with same speed. Then, velocity of A with respect to B is in South-East direction. Reason : Relative velocity between them is zero as their speeds are same.
