Edexcel GCSE Triple Science Physics Paper 2 2024 WITH QUESITIONS AND ANSWERS GRADED A+ Difference between scalar and vector: - CORRECT ANSWER--scalar = magnitude only -vector = direction and magnitude The only vector quantities are: - CORRECT ANSWER--acceleration -velocity -force -displacement -momentum -weight Force - CORRECT ANSWER--a push or a pull Balanced forces - CORRECT ANSWER--when 2 forces acting on an object are equal in size but act in opposite direction What is Newton...

According to Newton's Second Law of motion, if the net force acting on the object increases while the mass of the object remains constant, what happens to the acceleration? Hint: Remember F = m * a - correct answer Acceleration Increases If the earth were moved to half its current distance from the sun, how would the force of gravity by the sun on the earth change? Hint: Recall the form of the equation that you derived, earlier in the game: "gravitational acceleration (g) is proport...
