Forces 0.0 / 5 ? PhysicsForcesGCSEEdexcel Created by: Maddie-PCreated on: 28-01-21 12:25 What are forces measured in and using? Forces are measured in Newtons (N) using a Newton-meter. 1 of 11 What are some examples of common forces? Common forces include: Reaction, Upthrust, Thrust, Drag and Friction. 2 of 11 What is weight? Weight is a force measured in N. 3 of 11 What is mass? Mass is a quantity of matter measured in kg. 4 of 11 What is a difference between mass and weight? Weight varies due to position in space whereas mass is always constant. 5 of 11 What is the equation for weight? Weight = mass x gravitational field strength (on Earth gfs is approximately 10 N/kg) 6 of 11 How do you calculate overall forces? Forces in the same direction can be added together and forces in opposite directions can be subtracted from each other. 7 of 11 What are balanced forces? Balanced forces are equal and opposite forces which cancel each other out. 8 of 11 What objects have balanced forces? A stationary object has balanced forces and so does one with a constant velocity. 9 of 11 What are resultant forces? Unbalanced forces give a resultant force which is needed to accelerate or decelerate an object. 10 of 11 What is the equation for resultant force? Resultant force = mass x acceleration. 11 of 11
