# Physics Quiz: Test Your Knowledge of Force, Energy, and the Fundamentals of Nature

Questions:
1.What is the formula for calculating force?

2.What is the equation for calculating potential energy?

3.What is the equation for calculating kinetic energy?

4.What are the four fundamental forces of nature?

5.What is the difference between weight and mass?

1.The formula for calculating force is F = ma (force equals mass multiplied by acceleration).

2.The equation for calculating potential energy is PE = mgh (potential energy equals mass multiplied by gravity multiplied by height).

3.The equation for calculating kinetic energy is KE = 1/2 mv^2 (kinetic energy equals one-half mass multiplied by velocity squared).

4.The four fundamental forces of nature are gravity, electromagnetism, the strong nuclear force, and the weak nuclear force.
Mass is a scalar quantity that refers to the amount of matter in an object, while weight is a vector quantity that refers to the force exerted on an object due to gravity.

5.The weight of an object can change depending on the gravitational pull of its surroundings, while its mass remains the same.
