Enter a one- or two-word answer that correctly completes the following statement.
if the constant force is applied for a fixed interval of time (t), then the of the particle will increase by an amount (at)
if the constant force is applied over a given distance d, along the path of the particle, then the of the particle will increase by fd .
if the initial kinetic energy of the particle is ki , and its final kinetic energy is kf, express kf in terms of ki and the work w done on the particle. find kf

1. momentum

2. energy

3. Kf = Ki + W

Explanation:

1. If the constant force is applied for a fixed interval of time (t), then the momentum of the particle will increase by an amount (at).

Force F applied for a time t is called impulse and is given as F*t which is equal to the increase or decrease in momentum of an object.

2. If the constant force is applied over a given distance D, along the path of the particle, then the kinetic energy of the particle will increase by FD.

Work-Energy principle:

The principle of work and kinetic energy states that the work done by all forces acting on a particle (the work of the resultant force) equals the change in the kinetic energy of the particle.

3. Kf in terms of Ki and Work done:

We have Ki as the initial Kinetic energy of a particle. The Kinetic energy of a body changes when some work is done on it.

Work done on the particle is given as

Work done = Force * distance

W = F.D

So, final Kinetic energy = Initial Kinetic energy + Work done

Kf = Ki + FD

1) Velocity

2) Kinetic Energy

3)

Explanation:

When constant force is applied for a fixed interval of time then we have

now if the force is constant then we can use kinematics

so we will have

so here the velocity is increased by factor of "at"

Now the constant force is applied for some given distance D

so here we have work done by the force is given as

now by work energy theorem we can say that the total work done by all the forces must be equal to the change in kinetic energy

As per above work energy theorem we know that

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
