What force prevents an object from moving when pulled? Friction Does a heavier object move faster? The force of gravity is the weight of the body. Hence an object with greater mass feels greater force than the other one. So even if the slope is same for both objects, a massive object moves faster through […]

What is Charles Law in simple terms?
What is Charles Law in simple terms? Charles’s law, a statement that the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure remains constant. It is a special case of the general gas law and can be derived from the kinetic theory of gases under the […]

Can you get cancer from sitting in front of a heater?
Can you get cancer from sitting in front of a heater? We know what it is, but there have been very few direct sources of interference to the natural body functions, that result in the mutations of the cell divisions, that is commonly called ‘cancer’. Sitting in front of an “infra Red” heater, is not […]
What is the relationship between air pressure and weather?
What is the relationship between air pressure and weather? Atmospheric pressure is an indicator of weather. When a low-pressure system moves into an area, it usually leads to cloudiness, wind, and precipitation. High-pressure systems usually lead to fair, calm weather. How pressure affects the wind flow? Air Pressure and Winds Air that moves horizontally between […]
How do muscles get oxygen?
How do muscles get oxygen? Oxygen is supplied to the muscles via red blood cells. Red blood cells carry hemoglobin which oxygen bonds with as the hemoglobin rich blood cells pass through the blood vessels of the lungs. The now oxygen rich blood cells carry that oxygen to the cells that are demanding it, in […]
Is tens AC or DC?
Is tens AC or DC? A standard TENS unit typically delivers a low-frequency (<50 Hz) alternating current to a focused treatment area. Due to the nature of low-frequency, however, these signals have a low capacity to overcome skin resistance – resulting in these units only providing pain relief via the Gate Control Theory while being […]
What are the major features of introspection?
What are the major features of introspection? Introspection is closely related to human self-reflection and self-discovery and is contrasted with external observation. Introspection generally provides a privileged access to one’s own mental states, not mediated by other sources of knowledge, so that individual experience of the mind is unique. Why is introspection unreliable? Psychological research […]
How do you Operationalise variables examples?
How do you Operationalise variables examples? Operationalizing Variables For example, if we are concerned with the effect of media violence on aggression, then we need to be very clear what we mean by the different terms. In this case, we must state what we mean by the terms “media violence” and “aggression” as we will […]
