Formulas in Physics for 8th Grade

Here are some important formulas in physics for 8th grade:

1. Equation of Motion: The equation of motion relates the position, initial velocity, acceleration, and time of an object. The formula is:

x(t) = x0 + v0xt + axt^2/2 - x(t) represents the position of the object at time t. - x0 is the initial position. - v0x is the initial velocity in the x-direction. - ax is the acceleration in the x-direction.

2. Force: Force is the product of mass and acceleration. The formula is:

F = ma - F represents the force. - m is the mass of the object. - a is the acceleration.

3. Work: Work is the product of force and displacement. The formula is:

W = Fd - W represents the work done. - F is the force applied. - d is the displacement.

4. Power: Power is the rate at which work is done. The formula is:

P = W/t - P represents the power. - W is the work done. - t is the time taken.

5. Heat Transfer: Heat transfer is the product of mass, specific heat capacity, and change in temperature. The formula is:

Q = mcΔt - Q represents the heat transfer. - m is the mass of the substance. - c is the specific heat capacity. - Δt is the change in temperature.

6. Electric Charge: Electric charge is the product of charge density and volume. The formula is:

Q = ρV - Q represents the electric charge. - ρ is the charge density. - V is the volume.

7. Ohm's Law: Ohm's Law relates current, voltage, and resistance. The formula is:

V = IR - V represents the voltage. - I is the current. - R is the resistance.

These are just a few examples of formulas in physics for 8th grade. There are many more concepts and formulas to explore in the subject.
