The concepts of net force in a particular direction (thrust) and force per unit area (pressure) help explain these phenomena, as they relate to how force is distributed over an area.
Tiwari Academy Discussion Latest Questions
Cutting tools have sharp edges to concentrate the force applied over a smaller area, increasing the pressure and making it easier to cut through materials.
Trucks and motorbuses have much wider tyres to spread their weight over a larger area, reducing the pressure on the road surface and providing better stability and traction.
An army tank rests upon a continuous chain (tracks) to distribute its weight over a larger area, reducing the pressure on the ground and allowing it to move more easily over soft or uneven terrain.
A camel can run easily in a desert because its wide feet spread its weight over a larger area, reducing the pressure on the sand and preventing it from sinking.
The difference in mass causes the moon to exert a weaker gravitational force on objects compared to the Earth.
The weight of an object on Earth is the force with which the Earth attracts the object.
The gravitational force exerted by the moon on objects is directly related to its mass; since the moon’s mass is less than Earth’s, it exerts a weaker gravitational force.
The moon exerts a lesser force of attraction on objects because its mass is less than that of the Earth.
The weight of an object on the moon is defined as the force with which the moon attracts that object.
