experiment 1: kinematics

Question 1

why do things fall

Answer 1

due to the pull of gravity

Question 2

when a falling object is not affected by any restraints like friction and air resistance and falls under the influence of gravity alone

Answer 2

the object is said to be in free fall motion

Question 3

it is a form of motion experienced by an object or particle (a projectile) that is thrown near the earth’s surface and moves along a curved path under the action of gravity only (in particular, the effects of air resistance are assumed to be negligible)

Answer 3

projectile motion

Question 4

the horizontal displacement of the projectiles is called

Answer 4

range of projectiles

Question 5

range of projectiles depends on?

Answer 5

the object’s initial velocity

Question 6

formula to compute the
maximum height of the projectile:
horizontal range:
time of flight:

Question 7

formula to compute the
acceleration due to gravity
percentage error

Question 8

what is the value of the gravitational force

Answer 8

9.81m/s^2

Question 9

important numerical values to remember
weight and diameter of canon ball:
gravity:
angle of the canon:
initial velocity angle of the cannon:

Answer 9

weight and diameter of canon ball: 1.00kg, 0.10m
gravity: 9.81
angle of the canon: 25 degrees at first then increment of 10 degrees
initial velocity angle of the cannon: 5m/s then increment of 2m/s

Question 10

What equipment is used to measure the velocity and position

Answer 10

Explorer GLX
