Kinematics

Question 1

Kinematics

Answer 1

The study of motion

Question 2

Motion

Answer 2

a change in an object’s location as measured by a particular observer

Question 3

Distance (d)

Answer 3

This is the total length of the path travelled by an object in motion

Question 4

Direction

Answer 4

The line an object moves along from a particular starting point

Question 5

Vector

Answer 5

quantity that has magnitude (size) and direction (5m W)

Question 6

scalar

Answer 6

quantity that is only magnitude (size) (5m)

Question 7

Displacement (Δ⇀d)

Answer 7

change in position of an object

Question 8

d&d

Position (⇀d)

Answer 8

The distance and direction of an object from a particular reference point

Question 9

Acceleration (⇀a)

Answer 9

the rate of change of velocity.

Question 10

total (equation)

average speed

Answer 10

The average speed of a moving object is the total distance traveled divided by the total time taken.

Vavg = total d / total t

Question 11

change in (equation)

Average velocity

Answer 11

average Velocity is the total displacement (change in position) divided by the total time for that displacement

Vavg = Δd / Δt

Question 12

5 formulas

Answer 12

V2 = v1 + aΔt no Δd
v2^2 = v1^2 + 2aΔd no Δt
Δd = v1Δt + aΔt^2/2 no v2
Δd = v2Δt - aΔt^2/2 no v1
Δd = (v2 + v1 / 2)Δt no a

Question 13

Acceleration due to gravity

Answer 13

The acceleration that occurs when an object is allowed to fall freely

symbol - a/g
9.8m/s^2

Question 14

Free Fall

Answer 14

Free fall is the acceleration due to gravity in the absence of air resistance

Everything falls at the same rate

Question 15

Uniform Vertical Acceleration

Answer 15

Objects that move in the vertical direction (up and down; the y-axis; etc) experience acceleration due to gravity (g)

Question 16

what goes up must always go down

Projectile motion

Answer 16

The motion that an object experiences as it moves along a two-dimensional curved trajectory in response to gravity.
