![]() Weight is measured using a calibrated spring-balance (a newtonmeter).The weight of an object and the mass of an object are directly proportional.The weight of an object may be considered to act at a single point referred to as the object’s ‘centre of mass’.gravitational field strength, g, in newtons per kilogram, N/kg (In any calculation the value of the gravitational field strength ( g) will be given.).Weight = mass × gravitational field strength The weight of an object can be calculated using the equation:.The weight of an object depends on the gravitational field strength at the point where the object is.The force of gravity close to the Earth is due to the gravitational field around the Earth. Weight is the force acting on an object due to gravity.Students should be able to describe the interaction between pairs of objects which produce a force on each object.Examples of non-contact forces are gravitational force, electrostatic force and magnetic force.Examples of contact forces include friction, air resistance, tension and normal contact force.Non-contact forces – the objects are physically separated. contact forces – the objects are physically touching A force is a push or pull that acts on an object due to the interaction with another object. ![]() = mass × gravitational field strength × height The amount of gravitational potential energy gained by an object raised above ground level can be calculated using the equation: g.p.e.The kinetic energy of a moving object can be calculated using the equation: kinetic energy = 0.5 × mass × speed 2 E k = 1/2 mv 2.The length of the arrow represents the magnitude, and the direction of the arrow the direction of the vector quantity. A vector quantity may be represented by an arrow.Vector quantities have magnitude and an associated direction.Students should understand the following: Push and Pull Forces: What Makes Things Move?: self-paced video lesson uses a hands-on game with balls to explore how pushing and pulling affects an object's motion.Back to Teaching Rota Year 10 Forces & Motion.Teach About Newton's Laws of Motion: a resource collection for teaching about Newton's laws of motion.Do More!įor additional resources to explore forces of motion and related physics, see: Information is also provided about the aspects of NGSS Three Dimensional Learning addressed by each lesson. Teachers can view the associated NGSS performance expectations on the summary page for each lesson. Skydive Into Forces: make parachutes from tissue paper and string and experiment with toy skydivers to explore "invisible" forces like gravity and air resistance.Īll Lesson Plans at Science Buddies are NGSS-aligned.Two-Stage Balloon Rocket: build a multi-stage balloon rocket to investigate the science of space flight and Newton's laws of motion.(Students can use Google's free Science Journal app to record and graph acceleration data as part of the hands-on activity.) Push Harder - Newton's Second Law: build cars using craft materials and then use the cars to explore the relationship between force, mass, and acceleration.Paper Roller Coasters: Kinetic and Potential Energy: design and test paper roller coasters to explore kinetic and potential energy, conservation of energy, and friction.Balloon Car Lesson Plan: design, build, and race balloon-powered cars to experiment with kinetic and potential energy.These five free lesson plans each outline creative science activities that help students explore the forces of motion in tactile ways: Pair hands-on learning with engaging maker-inspired building projects like the ones described below, and your students will have fun putting forces of motion in action in the classroom and practicing engineering design at the same time. At Science Buddies, we know that getting kids hands-on with these concepts can be a powerful way to help them learn scientific concepts and make connections with other science lessons. Teaching elementary and middle school students about forces of motion, energy, and Newton's laws is an important part of standards-based science curriculum.
