The kinetic energy of a particle of mass m is found by taking one-half of the product of the mass (M) and the square of the veocity (V). write an expression for the kinetic energy of a particle.
Am i correct in writing
KE=1/2mv^2
yes
can u help me study for my algebra test that i have tomorrow??
sorry can't help you lol im so sorry but I just wanted to type on this about 4 years later hahahahah hope you did well though.
Of course! I'd be happy to help you study for your algebra test. Algebra can be challenging, but with practice and understanding of the concepts, you'll be able to tackle any problem. Let's start with some basic algebra principles and then move on to specific topics you need assistance with.
1. Key Algebra Principles:
- Variables: In algebra, letters are used to represent unknown quantities called variables. Variables can be replaced by actual numbers to solve equations.
- Operations: The basic operations in algebra are addition (+), subtraction (-), multiplication (*), and division (/). These operations follow specific rules.
- Equations: Equations are statements that show equality between two expressions. You can solve equations to find the value of the variable that satisfies the equality.
2. Linear Equations:
- One-step linear equations: Solve equations involving one operation (addition, subtraction, multiplication, or division) to find the value of the variable.
- Two-step linear equations: Solve equations that require two operations to find the value of the variable.
- Multi-step linear equations: Solve equations that require multiple operations to find the value of the variable.
3. Graphs and Functions:
- Coordinate planes: Understand how to read and plot ordered pairs on a coordinate plane.
- Linear functions: Understand the concept of slope-intercept form (y = mx + b) and how to graph linear functions.
- Systems of equations: Solve systems of equations with two or more variables using graphing, substitution, or elimination methods.
4. Exponents and Radicals:
- Exponents: Understand the laws of exponents, such as product of powers, power of a power, and zero exponent.
- Radicals: Simplify and perform operations with radicals, including addition, subtraction, multiplication, and division.
5. Quadratic Equations:
- Factoring: Factor quadratic expressions to solve quadratic equations.
- Quadratic formula: Use the quadratic formula (x = (-b ±√(b^2 - 4ac)) / 2a) to find the solutions of quadratic equations.
These are just some of the main topics in algebra. Let me know which specific topics or problems you need help with, and I'll be glad to explain them to you step by step. Good luck with your test!
