GCSE edexcel combined higher
physics paper 1 Questions And
Answers
/.Difference between a scalar and a vector? - Answer-✅vector has magnitude (size)
and direction, whereas scalar only has magnitude (size)
/.Give an example of some vector quantitites - Answer-✅force, velocity, displacement,
weight, acceleration and momentum
/.Give an example of some scalar quantities - Answer-✅speed, distance, mass, energy,
temperature and time
/.What does newtons first law say? - Answer-✅if the resultant force on a stationary
object is zero, the object will remain stationary. if the resultant force on a moving object
is zero, it'll continue moving at the same velocity
/.What is newtons second law? - Answer-✅Force = mass x acceleration
The larger the resultant force on an object, the more the object will accelerate
/.What's the difference between weight and mass? - Answer-✅mass is the amount of
stuff in an object, a scalar quantity
weight is the force acting on an object due to gravity
/.How is weight and how is mass measured? - Answer-✅mass is measured using a
mass balance (weighing scales) and weight is measured using a calibrated spring
balance
/.What is circular motion? - Answer-✅- if an object is travelling in a circle at a constant
speed, it is constantly changing direction so it is constantly changing velocity and is
therefore accelerating
- because it is accelerating, there must be a resultant force acting on it. this force acts
towards the centre of the circle
/.What is the name of the force that keeps something moving in a circle? - Answer-
✅centripetal force
