1. Fill in the blank /complete the sentence / answer the question. 1.1 In projectile motion, you should treat motion along the horizontal and vertical directions as being of each other. 1.2 If an object is in circular motion, in which direction does the acceleration vector point? 1.3 Write the equation that relates position and time for objects moving with constant accele ration: 1.4. A tennis ball is attached to a rope. I spin it above my head as shown below, and let it go at point A. Which way does the tennis ball go at the moment it is released? Circle one: up, down, left, or right. up Left Right down

Explanation / Answer

independent of each other

acceleration vector points towards the center of the circular motion

position and time are related by s= u*t+0.5*a*t^2 where s= displacement, u= initial velocity, t= time taken, a= acceleration

it continues the motion in the same direction it is moving when it is released, so it goes down

ask if unclear, upvote if understood to appreciate
