Force, Mass and Weight Dominos Game KS3

(0)
A dominoes game with questions and statements on forces and weight and mass instead of answers. Prior Knowledge Understand a force to be a pull or a push measured in Newtons (N). Examples of contact and non- contact forces. Forces change the speed, direction or shape of an object. All objects attract other objects and the bigger the object the bugger the attraction. The Earth’s attraction is called gravity which acts towards its centre and keeps its atmosphere in place and has a value of 10N/Kg. Mass is the amount of material in a body and is measured in kilograms (Kg). Gravity acts on a body’s mass and gives it weight which is measured in Newtons (N). The Moon’s gravity is on-sixth that of Earth and Jupiter is 2.5 times. What You Get 80 dominos Animated PowerPoint explaining the rules and how to play.

Sheets could be laminated to enable year-on-year use. Cut sheets into cards. Prior Knowledge Required Friction and air resistance act in the opposite direction to motion. The rougher the surface the more friction it causes. Friction produces heat. Lubricants, such as oil, reduce friction. Friction is useful when it provides grip. Friction is not useful when it slows things down and wastes energy. Friction is a force and is measured in Newtons (N). Air resistance is caused when the front of a moving object collides with air particles. Air resistance slows an object down, produces heat and wastes energy. Objects with a large surface area produce high air resistance. Streamlined shapes have low air resistance. A parachute has a large surface area and high air resistance. When the weight of a falling object equals the air resistance the body then falls with steady speed.
