Mention the expression for lorentz force and explain its terms

plase do this home work the screen shots are the problems i need it hand written there’s more pictures for the rest of the questions but the site won’t let me upload it

1. Define Acceleration

In physics, acceleration is a vector quantity that describes how quickly an object’s velocity changes. It is not just about how fast an object is moving, but how its speed or direction evolves during a specific interval.

2. Identify the Mathematical Formula

Acceleration (

) is calculated by dividing the change in velocity (

) by the time interval (

) during which the change occurred:

Where:

is the final velocity.

is the initial velocity.

is the time taken.

• Deriving the First Law: If the external force $$ is zero, then . Since mass ($$m) can’t be zero, the acceleration (a$$) must be zero. This means an object at rest stays at rest, and an object in motion stays in motionwhich is exactly what the First Law states.
• Deriving the Third Law: By considering an isolated system of two interacting particles and applying the Second Law (in terms of momentum), you can show that the force exerted by the first body on the second is equal and opposite to the force exerted by the second on the first (F12 = F21).

Thermodynamics is a branch of physics that studies heat, temperature, and energy, and how they move or change in a systemIt

explains things like:

Why hot objects cool down

How engines work

How heat turns into energy

Momentum is a moving object that can havr a large momentum if it has a large mass, a hugh velocity or both

formula for momentum:p=mv

p=momentum

m=mass

v=velocity

Science is the study of how the world works using observation and experiments. It helps us understand nature and solve problems.

Physics is a branch of science that focuses on matter, energy, motion, and forces. It explains how things move, why objects fall, how electricity works, and even how the universe behaves.
