Question

Please circle or highlight the correct answer in the following questions: 1. Which of the following statements is false? a. Kinematics is the part of mechanics concerned with motion b. Displacement has an associated distance and direction c. The speed is how fast an object is travelling and in what direction d. Acceleration is the rate of change of velocity 2. You throw a tennis ball straight upward and watch as it rises to the highest point in its trajectory. At this point you can say that: a. The displacement, velocity and acceleration of the ball are all zero b. The ball has a non-zero displacement but both velocity and acceleration are žero c. The ball has non-zero displacement and acceleration but the velocity is zero d. The displacement, velocity and acceleration are all non-zero

Explanation / Answer

a) true

kinematics is a branch of mechanics that describes the motion of bodieswith out considering the force

b) displacement is a vector . it has both magnitude and direction

displacement is a shartest distance

so it is true

c) speed is a scalr it doesnot have any direction

so it is false

d) true

2) non zero displacement and acceleration but at max height velocity is zero
