True False Objects can have equal speeds without having equal velocities Objects can have equal velocities without having equal speeds. Constant velocity implies constant speed. If you know the distance an object travels and the time it takes to do so, Constant speed implies constant velocity you can determine the object's velocity If you are given an object's velocity, you can definitely determine its speed Answer Bank FS 3 4 5 8

Answer 1

statement 1-objects can have equal speeds without having equal velocities-true,the magnitude of velocity gives the speed,therefore two velocities can have the same magnitude irrespective of the direction

statement-2-objects can have equal velocities without having equal speeds-false-since for the two velocities to be equal ,their magnitude(speed) and directions must also be same,which implies they cant have equal velocities while having unequal speeds

statement-3-constant velocity implies constant speed-true-since the velocity is constant ,that means both magnitude and direction are constant,so speeds are constant

statement-4-if you know the distance an object travels and the time it takes to do so,you can determine the object's velocity-false-since distance is a scalar quantity which cannot be used to calculate a vector quantity(velocity)

statement-5-if you are given an object's velocity,you can definitely determine its speed-true-since we are given with velocity,that means both magnitude and direction are given,and magnitude is nothing but the speed with which particle or body is moving
