What force is responsible for the painful difference between sliding on pavement and sliding on grass?
friction: the force that resists relative motion between two bodies in contact.
Is the friction between car tires and pavement greater when the car is at rest or in motion?
Interesting - static friction is greater than moving friction; but if the car is not in a skid, then the part of the tires in contact with the road is not moving ... thus static friction holds in both cases.
When you stand on one foot the pressure you exert is your weight divided by your shoe size?
The pressure you exert when standing on one foot is actually your weight divided by the area of contact between your foot and the ground. Shoe size is not a relevant factor in this calculation as it does not affect the pressure. The smaller the area of contact, the greater the pressure exerted on the ground.
What is the relationship between force area and pressure?
pressure = force / area Therefore pressure and force are directly proportional, meaning... The greater the force the greater the pressure and the lower the force the lower the pressure
Will the speed of a wind be greater if the difference in air pressure is large or small?
The speed of the wind is typically greater when there is a larger difference in air pressure between two points. This is because wind moves from areas of high pressure to areas of low pressure, and the greater the contrast, the stronger the wind will be as it tries to equalize the pressure.
What exerts greater pressure on the floor standing flat footed or standing on tip toe?
Standing on tip toe exerts greater pressure on the floor compared to standing flat footed. This is because less surface area of contact between the feet and the floor means the body's weight is concentrated on a smaller area, resulting in increased pressure.
Is it true that the larger the surface area and the more pressure means more friction?
Yes, in general, an increase in surface area and pressure can lead to an increase in friction between two surfaces. This is because a larger surface area and higher pressure result in more points of contact between the surfaces, which can generate greater frictional forces.
What is the relationship between contact force and friction?
Contact force is the force exerted between two surfaces in contact with each other. Friction is the force that resists the motion of an object sliding or rolling over a surface. Contact force contributes to the frictional force between two objects - the greater the contact force, the greater the frictional force.
What is a pressure gradient and how is it related to air movement?
Pressure gradient is the rate of pressure change as you change position, not just the difference between the lowest pressure and the highest pressure, but how great (or small) the physical distance between them. Since it the pressure difference that make air flow (wind) the greater the pressure gradient, the greater the wind.
What is true about the abolition movement?
it increased contact between the races, leading to greater understanding
Why will the balloons touched each other if you blow hardly in between them?
If you blow between them, you decrease the pressure of the air between the balloons. The air around them, which has greater pressure, will force them to approach each other.
What is the relationship between pressure and volume in liquids.Pressure is directly proportional to the volume. If the volume is greater the pressure also will be greater in liquids. Is it correct?
Not quite. In liquids, the relationship between pressure and volume is not as simple as in gases, where there is a direct proportionality. In liquids, the relationship between pressure and volume is influenced by factors such as density and temperature, in addition to volume. So, it is not accurate to say that pressure is directly proportional to volume in liquids.
