1.5 Forces
1.5.1 Balanced and unbalanced forces
1 Identify and use different types of force, including weight (gravitational force), friction, drag, air resistance, tension (elastic force), electrostatic force, magnetic force, thrust (driving force) and contact force
2 Identify forces acting on an object and draw free-body diagram(s) representing the forces
3 State Newton’s first law as ‘an object either remains at rest or continues to move in a straight line at constant speed unless acted on by a resultant force’
4 State that a force may change the velocity of an object by changing its direction of motion or its speed
5 Determine the resultant of two or more forces acting along the same straight line
6 Recall and use the equation
resultant force = mass × acceleration
F=ma
7 State Newton’s third law as ‘when object A exerts a force on object B, then object B exerts an e
