Mechanics - something

Question 1

Projectile

Answer 1

and object in freefall

Question 2

Freefall

Answer 2

when the only force is downward gravity ??

Question 3

Projectile Motion

Answer 3

Parabola shape.

Two objects cover the same vertical distance under constant downward acceleration regardless of horizontal motion.

(Air resistance is negligible until 100ms-2)

Question 4

Newton’s first law

Answer 4

When resultant force = 0, velocity is constant/ acceleration = 0.

Question 5

Newton’s second law

Answer 5

Acceleration of object is proportional to resultant force acting on it (F=ma)

Question 6

vector velocity split into horixontal and vertical
