Can a charged particle moved through a magnetic field without experiencing any force?
If the motion of the particle is parallel to the direction of the field, then the force on the particle will be zero. This is an unstable condition, though. Even the slightest deviation from parallel will give a tiny force to the particle, which nudges it farther away from the parallel direction.
How are the four fundamental forces in physics important in explaining and predicting motion?
These four interactions determine changes in particle motion. If force is acted on an object, then its motion is going to change from what it was before the force acted.
What requirement must be satisfied by a force acting on a particle in order for the particle to undergo simple harmonic motion?
It must be directly proportional to the displacement.
Does centrifugal force exist?
No, centrifugal force is fictitious force, peculiar to circular motion, that is equal but opposite to the centripetal force that keeps a particle on a circular path.
Give you an example of electrical force?
Motion of ions in a battery, or the motion of a charged particle in cyclotron; muscle contraction in tissue, the frog's leg twitch.

What factors affect the increase of the centripetal force on a particle in uniform circular motion?
The centripetal force on a particle in uniform circular motion increases with an increase in the mass of the particle or the speed at which it is moving. It also increases if the radius of the circle decreases, as the force required to keep the particle in the circular path becomes greater when the circle is smaller.
How can you show that force certainly acts on a particle moving along circular path?
If no force acts on a particle, that particle will either be motionless, or will move in a straight line; this follows from Newton's laws of motion. When a particle is moving in a circular path, the direction of its motion is constantly changing, and to change the direction of motion requires force. We know that force equal mass times acceleration, which is the basis of all physics, as originally stated by Newton. So if a mass is being accelerated, then force is being applied. That is an inescapable conclusion. And only acceleration can change the direction in which a particle moves.

3 What factors affect the increase of the centripetal force on a particle in uniform circular motion?
Speed, friction, momentum, and conservation of motion
What requirement must be satisfied by a force acting on a particle in order for the particle to undergo simple harmonic motion?
It must be directly proportional to the displacement.
Does centrifugal force exist?
No, centrifugal force is fictitious force, peculiar to circular motion, that is equal but opposite to the centripetal force that keeps a particle on a circular path.
How does the mass affect the force of an object?
According to Newton's Second Law of Motion,F=ma, where F is the applied force, m is the mass of the particle and a is acceleration of the particle. Thus, Force, F is directly proportional to mass.

Can a charged particle move through a magnetic field without experiencing any force?
No, the particle has the following forces f= qvB= - qv.B + qvxB, the first force is a scalar force when the particle is parallel to the field and teh second force is avector force when teh particle is perpendicular to the field. If the particle is not neither parallel or perpendicular to the field, both the scalar and vector forces will be experiencd.
What is the particle motion?
Brownian motion
How must the net force depend on the speed of the moving object in order to obtain uniform circular motion?
The force required to keep a body to be in a uniform circular motion is known as centripetal force means centre seeking force. This centripetal force is directly proportional to the square of the speed of the particle.
