Uniformly Accelerated Motion

Question 1

Acceleration must be constant for these equations to work true or false

Answer 1

True

Question 2

acceleration is zero
No horizontal forces (ignoring air resistance, of course)
•Therefore, horizontal velocity does not change

Answer 2

Horizontal

Question 3

acceleration is equal to the acceleration due to gravity (g = –9.8 m/s2)

Answer 3

Vertical

Question 4

A constant attractive force (Newton’s Law of Gravitation)

Answer 4

Vertical

Question 5

person falls from a wall while rock climbing.
We can predict their motion by using the
previous equations.

Answer 5

Vertical Projectiles

Question 6

Answer 6

parabolic path

Question 7

Vertical velocity at the peak of the projectile’s flight will be exactly

Answer 7

Zero

Question 8

velocity is constant (ignoring air resistance)

Answer 8

Horizontal
