Questions & Answers {Grade A} 100%
Correct
What factors affect speed? - correct answer Fitness of the person
Age of the person
Distance travelled
Terrain
Climate
Gender of the person
What factors affect wind speed? - correct answer Temperature
Atmospheric pressure
Any large buildings or structures nearby e.g. Forests reduce wind speed travelling
through them
Acceleration - correct answer change in velocity in a certain amount of time
Equation for Acceleration - correct answer Acceleration (m/s²) = Change in Velocity
(m/s) / Time (s)
A=Δv/t
,What is deceleration? - correct answer Negative acceleration - when something slows
down, the change in velocity is negative
What is constant acceleration? - correct answer Uniform acceleration - acceleration
due to gravity is uniform for objects in free fall
Equation for Uniform Acceleration - correct answer Final velocity² (m/s) - Initial
velocity² (m/s) = 2 x Acceleration (m/s²) x Distance (m)
V²-u²=2as
Distance-Time Graphs - Features - correct answer 1) Gradient = speed
2) Flat sections = object is stationary
3) Straight uphill sections = object is travelling at a steady speed
4) Curves = object is accelerating or decelerating
5) Steepening curve = object is speeding up
6) Levelling off curve = object is slowing down
Vector quantities - correct answer have magnitude and direction
Examples of vector quantities - correct answer force, velocity, momentum,
acceleration
, Scalar quantities - correct answer Only have magnitude and no direction
Examples of scalar quantities - correct answer speed, distance, time
Vectors - correct answer represented by an arrow - the length of the arrow shows the
magnitude. The direction of the arrow shows the direction of the quantity
A force is - correct answer a push or pull on an object that is caused by it interacting
with something
When two objects are touching for the force to act, its a .... - correct answer contact
force
Examples of contact forces - correct answer friction, air resistance, tension in ropes.
Etc
If the objects do not need to be touching for the force to act, the force is a ...... - correct
answer non contact force
Examples of non contact forces - correct answer magnetic force and gravitational
force
