Workforce, Energy, and Forces Quiz

• The topic of discussion is workforce and energy.
• Activities in daily life involve pushing or pulling objects, which results in the application of force.
• Two types of forces exist: contact and non-contact.
• Contact force is the result of two or more objects coming into contact, with examples including a person pushing a box, friction, and a table supporting an object.
• Non-contact force occurs when objects do not come into physical contact, with examples including an apple falling from a tree, a football in mid-air, and paper being attracted to a magnet or comb.
• Work is done when a force is applied to an object, resulting in movement, and can be positive, negative, or zero.
• The formula for calculating work is work = force x distance, with the standard unit of measurement being joules.
• Energy is the ability to perform work and is essential for everyday tasks.
• Energy can be obtained from food, such as green vegetables, fruits, and nuts.
• The gravitational force keeps the earth orbiting around the sun, and the earth functions like a strong bar magnet with a magnetic north and south.
