Vectors are quantities with a [blank_start]magnitude and a direction[blank_end].
Responda
magnitude and a direction
magnitude only
Questão 5
Questão
Distance measures the [blank_start]length of the path travelled[blank_end]. Position is the [blank_start]straight line distance[blank_end] between an object and a [blank_start]reference point[blank_end]. Displacement gives us the [blank_start]change in position[blank_end] of an object from a reference point.
Responda
length of the path travelled
straight line distance
reference point
change in position
straight line distance
length of the path travelled
reference point

Questão 6
Questão
What is the difference between the notation for velocity and speed?
Responda
Velocity has an arrow on top of the notation
Velocity is written with a "v" instead of an "s"
Questão 7
Questão
Convert from 30 km/(h×s) to m/s^2.[blank_start]________[blank_end]
The slope of a position-time graph gives us the [blank_start]velocity[blank_end] and the slope of a velocity-time graph gives us the [blank_start]acceleration[blank_end].
Responda
velocity
acceleration
Questão 9
Questão
The area under a velocity-time graph gives us the change in the acceleration.
Responda
True
False
Questão 10
Questão
The formula (d = ½(Δv·Δt)) is not useful when converting from a displacement to a velocity graph.
Responda
True
False
Questão 11
Questão
Determine the total displacement an object travels if it travels 5 m [N30°E] and then 4 m [N10°W].[blank_start]________[blank_end] m [[blank_start]_______[blank_end]]
Responda
8.5
N18E
Questão 12
Questão
Determine the time that it take a projectile fired at 8 m/s [30° above the horizontal] from a cliff that is 100 m above the ground to reach the ground.[blank_start]_______[blank_end]s
Responda
4.9
