Relative velocity refers to the velocity of an object with respect to another object. It is the difference between the velocity of the first object and the velocity of the second object, both measured with respect to the same frame of reference. For example, if a car is moving with a velocity of 60 km/h…
Uniform circular motion refers to the motion of an object moving in a circular path at a constant speed. In uniform circular motion, the object moves in a circle with a constant radius and a constant angular velocity. This means that the object travels the same distance along the circumference of the circle in equal…
A projectile is any object that is thrown, shot, or launched into the air, and that moves along a ballistic trajectory. Projectiles are subject to the force of gravity, which causes them to follow a curved path known as a parabola. The motion of a projectile can be described by its initial velocity, angle of…
Cartesian coordinates are a system of describing the position of a point in space using three numbers, typically denoted as (x, y, z). The x-coordinate represents the distance from the point to the yz-plane (a plane perpendicular to the x-axis), the y-coordinate represents the distance from the point to the xz-plane (a plane perpendicular to…
Two dimensions refer to a two-dimensional space, which is a flat plane that has two axes, usually referred to as the x-axis and the y-axis. These axes are perpendicular to each other and intersect at a point called the origin. In a two-dimensional space, any point can be located using a set of coordinates that…
Kinematics in one dimension refers to the study of motion of an object in a straight line. It involves analyzing the position, velocity, acceleration, and time of an object as it moves along a single axis. Kinematics is an important branch of physics that forms the basis of many other fields, such as mechanics and…
A post office box (PO Box) is a secure mailbox that is rented by individuals or businesses from a post office. It is typically used as an alternative to a physical street address for receiving mail and packages. PO boxes are especially useful for those who move frequently, live in areas with unreliable mail delivery,…
To determine the specific resistance of the material of a wire using a meter bridge, you will need the following equipment: Here are the steps to follow: You have now determined the specific resistance of the material of the wire using a meter bridge. What is Required General Specific resistance of the material of a…
An ammeter is an instrument used to measure the electric current in a circuit. It is typically connected in series with the circuit so that all of the current flows through it. The ammeter measures the flow of electrical charge in amperes (A) and is usually calibrated in milliamperes (mA) or microamperes (μA) for smaller…
Ohm’s law states that the current through a conductor between two points is directly proportional to the voltage across the two points. This relationship is often expressed as: I = V/R where I is the current in amperes, V is the voltage in volts, and R is the resistance in ohms. To verify Ohm’s law…
