On The Move

Question 1

What is a projectile

Answer 1

Any object where three key principles apply
1the acceleration of the object is always g and acceleration only affects the vertical momentum of the object
2 the horizontal velocity of the object is constant because there is no acceleration
3 the motions of the vertical and horizontal directions are independent

Question 2

What are the two equations for vertical projection

Answer 2

V=u-gt

Y= ut-1/2gt^2

Question 3

what is the area under a speed time graph

Answer 3

distance travelled by an object

Question 4

what is the gradient of a velocity time graph

Answer 4

acceleration

Question 5

what is the area under a velocity time graph

Answer 5

displacement of the object from it’s starting position
