A net external force acts on a particle This net force is not equal to zero is this sufficient information to conclude that the velocity of the particle changes?
Yes, if a net external force is acting on a particle, it will cause the particle's velocity to change according to Newton's second law (F=ma). The direction of the velocity change will be in the direction of the net force.
A net force acts on a particle this net force is not equal to zero is this sufficient information to conclude that the speed of the particle changes?
Yes, one of Newtons Laws (I've forgotten which one) states that F=ma, which can also be written a=F/m. As long as F (the net force) is not zero, the particle will experience acceleration, and hence, a change in its velocity.
How does particle behavior change as an object changes from a solid?
How does particle behavior change as an object changes from a solid to liquid to gas
Is the speed of the particles in a substance changes when the temperature changes?
Yes, in fact, particle movement is what heat is.
The smallest particle of an element that can enter into chemical changes?
atom
What particle changes is required to make an element an isotope?
neutrons
What causes variation in velocity of particle?
Variation in velocity of a particle can be caused by external forces acting on the particle, such as gravity or friction. Additionally, changes in direction or acceleration can also lead to changes in velocity. In a vacuum, an object will continue at a constant velocity due to inertia.
Which particle does not change in amount in an atom?
The particle in an atom that cannot change is the number of protons. If that changes, it is no longer the same element.
When an atom loses or gain this type of particle the mass nbr changes?
electrons
What causes variation in velocity of a particle?
Variation in velocity of a particle can be caused by changes in the magnitude or direction of the force acting on the particle, inertia of the particle, or interactions with other particles in the system. Additionally, external factors such as friction, air resistance, and gravitational forces can also influence the velocity of a particle.
The speed of the particles in a substance change when what changes?
electrons
What happens in a nuclear charge when the starting particle changes its number of protons?
It changes the element! More protons more positive charge!
