GCSE EDEXCEL PHYSICS PAPER 1QUESTIONS AND ANSWERS WITH
SOLUTIONS 2024
- ANSWER
define vector - ANSWER quantise with magnitude and direction
List some vectors (6) - ANSWER force, velocity, displacement, weight, acceleration, momentum
define scalar - ANSWER quantities with magnitude but no direction
list some scalar quantities (6) - ANSWER speed, distance, mass, energy, temperature, time
define velocity - ANSWER speed in a given direction
distance = - ANSWER s x t
walking speed = - ANSWER 1.4m/s
running speed = - ANSWER 3m/s
cycling speed= - ANSWER 5.5m/s
cars in towns speed - ANSWER 13m/s
cars on motorway speed - ANSWER 31m/s
trains speed - ANSWER (up to) 55m/s
,wind speed - ANSWER 5-20m/s
speed of sound in air - ANSWER 340m/s
define acceleration - ANSWER change in velocity in a certain length of time
acceleration = - ANSWER (v-u)/t
what causes acceleration of all objects in freefall to be equal - ANSWER gravity
accelerate due to gravity = - ANSWER 10m/s/s
uniform acceleration = - ANSWER v2-u2=2xaxx
gradient on distance time graph = - ANSWER speed
average speed = - ANSWER total distance/time
gradient of velocity time graph = - ANSWER acceleration
area under velocity/time graph = - ANSWER distance
Newton's first law - ANSWER a force is needed to change motion
If the resultant force on a stationary object is zero - ANSWER object will remain stationary
if resultant force on an moving object is zero - ANSWER it will continue to move at the same speed
, five forms of an acceleration - ANSWER starting, stopping, speeding up, slowing down, changing
direction
the larger the resultant force on an object - ANSWER the more it accelerates
relationship between force and acceleration - ANSWER directly proportional
force = - ANSWER massxacceleration
Newton's second law - ANSWER f=mxa
safety features in cars designed to increase collision time to reduce force are - ANSWER seatbelt, airbags,
crumple zones
how does a vehicle skid (brakes) - ANSWER brakes do work on wheels, energy transferred from kinetic to
thermal stores, brakes overheat
define mass - ANSWER amount of stuff in an object
define weight - ANSWER the force acting on an object due to gravity (caused by the gravitational field)
unit of weight - ANSWER newtons
what is the single point where the force of weight acts on an object called - ANSWER centre of mass
weight = - ANSWER mass x gravitational field strength
If an object is travelling in a circle - ANSWER constantly changing direction and velocity so must be
accelerating
