Plotting projectile displacement, acceleration, and velocity as a function of time.
Plotting projectile displacement, acceleration, and velocity as a function of time.
The potential energy between two objects due to long-distance forces can be thought of as being stored in a field. When the objects move due to the field forces, the energy stored in the field decreases
Figuring out the horizontal displacement for a projectile launched at an angle.
Visualising position, velocity and acceleration in two-dimensions for projectile motion.
Electrical devices convert the electrical energy carried by the charges into other types of energy such as heat, sound, and motion. Components in the appliance resist the flow of charge and are referred to as resistors. In this unit1 you will understand what resistance is, the factors that affect the resistance and the relationship between resistance and current.
Most of us use electricity every day in many different ways so it is important that we understand the dangers, or hazards, associated with electricity and we know how to use it safely.
In this lesson you will learn about:
What are simple machines? Simple machines are tools that make work easier. They have few or no moving parts. These machines use energy to do work with one movement. They make our work easier by letting us use less mechanical effort to move an object.
