What happens to the speed at which molecules are moving?

The speed at which molecules are moving increases as temperature increases, since temperature is a measure of the average kinetic energy of the molecules. This leads to an increase in the rate of collisions between molecules and an increase in the overall kinetic energy of the system.


Will the mass or weight increase when you eat something?

When you eat something, the mass of your body temporarily increases due to the addition of the food. This increase in mass will also correspond to an increase in weight, as weight is the force exerted by gravity on that mass. However, once the food is digested and metabolized, the mass and weight will decrease as your body processes and eliminates waste.


How do the magnitudes of weight and air drag compare?

They are totally unrelated. Weight is basically the force of attraction between the Earth and the body. It doesn't depend on shape. Air drag depends on how fast a body is moving through air and depends on its shape. There is one interesting example : when a parachute, or even an object falls under gravity for long enough, it may reach a speed where the air drag equals the weight - and then further acceleration ceases and the speed is called the terminal velocity. The terminal velocity therefore depends critically on the shape, and the weight.


State any one factor which determines the kinetic energy of a body?

One factor affecting the kinetic energy of a particle (or body) in is the viscosity of the medium through which that particle moves


Does mass change after you eat two cans of food?

Yes, your mass will increase after eating two cans of food due to the weight of the food entering your body. This increase in mass is temporary until your body digests and processes the food.

Why does weight increase as speed increases?

Weight does not actually increase as speed increases. However, the sensation of weight can appear greater when moving faster due to the additional forces acting on the body, such as air resistance or acceleration forces. This can give the perception of increased weight, even though the actual weight of the object or person remains the same.


How many times centripetal force will increase if the angular speed of a body moving with uniform speed moving in a circle is increases?

Centripetal acceleration, and therefore centripetal force, is proportional to the square of the angular velocity. For example, if you increase the angular velocity by a factor of 10, the centripetal force will be increased by a factor of 100.


What is the work done by the weight if a body is moving at constant speed over a firctionless surface?

If a body is moving at constant speed over a frictionless surface, the work done by the weight of the body is zero. This is because the weight force acts in the downward direction, perpendicular to the direction of motion, so there is no displacement in the direction of the weight force for work to be done.


Does the acceleration of the body always change the speed of the body?

Not always. If a moving body changes direction without changing speed then we still say it has had an acceleration. Tie a weight to a piece of string and swing it around your head at a steady speed. The weight is accelerating towards you all the time. If the string were to break, the weight goes on in a straight line unaccelerated.


Does body weight increase from insulin injection?

No, body weight does not increase drom an insulin injection.


Example of ways increasing friction?

Increasing friction can be achieved by using materials with rougher surfaces, increasing the weight pressing the surfaces together, or increasing the normal force acting between the surfaces. Additionally, applying more force parallel to the surfaces in contact can also increase friction by creating more interlocking between the surfaces.


What is the speed and direction of a moving body called?

The speed and direction of a moving body is called velocity. Velocity is a vector quantity that specifies both the speed of an object and the direction in which it is moving.


What must change when a body is accelerating?

A moving body can be accelerated by applying a force. This force will act to increase velocity, decrease velocity or change the direction the body is moving. All three of these are acceleration.


What happens to the velocity of a moving body if you change the speed at which the body is moving?

The velocity changes. called acceleration.


Does speed increase when the net force is opposite to the direction of motion?

When the net force on a body is in the opposite direction to the motion of the body the speed of the body will never increase rather retardation will take place and the body will lose its speed.


What happens to the velocity of a moving body if you change the direction in which the body is moving?

It depends how you changed the direction of the body. If the body is hit by an external force in the direction of motion, the velocity should increase. If the body is hit by an external force in the opposite direction of motion, velocity will decrease.


What would be the shape of a speed time graph of a body moving with variable speed?

If a body is moving with variable speed, then the only thing you can say aboutits speed/time graph is that the graph is not a straight, horizontal line.
