Basic primer on Newton's First Law of motion.

Newton's Laws of Motion

Newton's second law of motion is F = ma, or force is equal to mass times acceleration. Learn how to use the formula to calculate acceleration.

Learn about Newton's third law of motion, which states that for every action there is an equal and opposite reaction. Look at multiple examples that illustrate this law, including pushing a block on ice, pushing against a desk, walking on sand, how rockets work, and how an astronaut could save themselves from drifting in space.

• Predict how current will change when resistance of the circuit is fixed and voltage is varied.
• Predict how current will change when voltage of the circuit is fixed and resistance is varied.

You want a projectile to fly as far as possible, at which angle should you launch it? We'll start with formulas for the initial velocity.

This is a short tutorial on how to define and measure the perimeter of shapes

By the end of this course you will be able to:

1. Define the terms perimeter and area
2. Find the perimeter of any polygon
3. Find the perimeter and area of a trapezium, parallelogram, rectangle and square
4. Find the area of a triangle
5. Find the perimeter and area of a circle

Plotting projectile displacement, acceleration, and velocity as a function of time.

Figuring out the horizontal displacement for a projectile launched at an angle.
