## How does a mousetrap car work?

A mousetrap powered car is a vehicle that is powered by the energy of a wound-up mouse trap’s spring. Once the drive axle and mouse trap are released the string is pulled from the drive axle by the mouse trap and this causes the drive wheels to rotate.

## What is the basic principle of physics?

Basic principles of physics According to physics, the physical laws of matter, energy and the fundamental forces of nature govern the interactions between particles and physical entities (such as planets, molecules, atoms or the subatomic particles).

## How does the length of the lever arm affect a mousetrap car?

Making the length of the mouse trap’s lever arm longer will decrease the pulling force but increase the amount of string that can be pulling from the drive axle. Shortening the length of the lever arm increases the pulling force but decrease the amount of string that can be pulled from the drive axle.

## How does Newton’s 3rd law apply to a mousetrap car?

Newtons third law affects the car because for every action there is an equal and opposite reaction. That means that as the car is rolling that friction is pushing against it with not as much force so the car still moves. But as the car keeps going the forces equal out and the car slows down until it finally stops.

## What is the king of science?

“Physics is the king of all sciences as it helps us understand the way nature works. It is at the centre of science,“ he said. As he spoke about the transformation of particle physics over the last 50 years, he said his love of the subject has only grown with each passing year.

## What are the topics in nuclear physics?

This includes nuclear power, nuclear weapons, nuclear medicine and magnetic resonance imaging, industrial and agricultural isotopes, ion implantation in materials engineering, and radiocarbon dating in geology and archaeology. Such applications are studied in the field of nuclear engineering.

## What makes a mousetrap car go further?

Using large rear wheels allow one rotation of the axle to take the car a much further distance. In other words, a given length of the string from the mousetrap moves the car a greater distance.

## What is SI unit of speed?

The S.I unit of speed is metre/second or metre per second i.e m s − 1 m\ s^{-1} m s−1.

## What is the purpose of a mousetrap car?

A mousetrap car uses the stored energy of a mousetrap spring to generate forward motion. In competitions, the goal of the mousetrap car is to achieve as much forward motion as possible, on a flat surface and/or on an inclined surface. In other words, the goal is to maximize the distance traveled on both these surfaces.

## What is SI unit of velocity?

Velocity is a physical vector quantity; both magnitude and direction are needed to define it. The scalar absolute value (magnitude) of velocity is called speed, being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per second (m/s) or as the SI base unit of (m⋅s−1).

## How is energy conserved in a mousetrap car?

When a mousetrap is set, the spring in the center is compressed, becoming a source full of potential energy. This energy is being stored, not used, but as soon as the trap is released, it is converted to kinetic energy (the energy of motion) that propels the snapper arm forward.

## Who is the Nuclear Man of India?

Homi Jehangir Bhabha (30 October 1909 – 24 January 1966) was an Indian nuclear physicist, founding director, and professor of physics at the Tata Institute of Fundamental Research (TIFR).

## Who is father of nuclear physics?

Ernest Rutherford

## Did Sir Isaac die a virgin?

Newton was rigorously puritanical: when one of his few friends told him “a loose story about a nun”, he ended their friendship (267). He is not known to have ever had a romantic relationship of any kind, and is believed to have died a virgin (159).

## What is the 3 laws of motion?

The laws are: (1) Every object moves in a straight line unless acted upon by a force. (2) The acceleration of an object is directly proportional to the net force exerted and inversely proportional to the object’s mass. (3) For every action, there is an equal and opposite reaction.

## What is the physics behind a mousetrap car?

The basics The mousetrap storespotential energyin the form of the spring. That potential energy is converted into kinetic energy in the form of the arm rotating forward. The arm pulls on the wound-up string, which turns the drive wheel dowel, which is connected to the wheels, which makes the car drive forward.

## What are the 7 basic SI units?

The seven SI base units, which are comprised of:

• Length – meter (m)
• Time – second (s)
• Amount of substance – mole (mole)
• Electric current – ampere (A)
• Temperature – kelvin (K)
• Luminous intensity – candela (cd)
• Mass – kilogram (kg)
