What else can I help you with?
When the distance travelled by a body is directly proportional to time then it is travelling with?
constant speed.
What is the definition of hookes law is science physics?
Hooke's Law states that the force needed to extend or compress a spring by a distance is directly proportional to that distance. Mathematically, it is expressed as F = kx, where F is the force applied, k is the spring constant, and x is the distance the spring is stretched or compressed.
What is Rate of fall of temperature of the body is directly proportional to?
The rate of fall of temperature of the body is directly proportional to the temperature difference between the body and its surroundings, the surface area of the body exposed, and the thermal conductivity of the material between the body and its surroundings.
What is the difference between distance travelled by a body and its displacement and explain with a diagram?
Distance travelled by a body is the total length of the path covered, while displacement is the shortest distance between the initial and final positions of the body (measured in a straight line). In a diagram, imagine a curved path with turns and loops - the total length of this path is the distance travelled, while the straight line connecting the start and end points represents the displacement, which is the shortest distance between the two points.
Define speed as a rate and define velocity as speed in a given direction?
Velocity of a body is the distance travelled by it per unit time in a given direction. Velocity is a vector quantity as it has both magnitude as well as direction. Speed of a body gives us idea of how slow or fast a body is moving. Speed of a body is the distance travelled by it per unit time. formula for speed is given by : Distance travelled/Time taken
When the distance travelled by a body is directly proportional to time then it is travelling with?
constant speed.
What is newton's cooling law?
rate of change of cooling is directly proportional to the temperature distance between the body and the surrounding at the instant.
What is the definition of hookes law is science physics?
Hooke's Law states that the force needed to extend or compress a spring by a distance is directly proportional to that distance. Mathematically, it is expressed as F = kx, where F is the force applied, k is the spring constant, and x is the distance the spring is stretched or compressed.
Is there a force of attraction between molecules?
yes,there is a force of attraction and this force is included in universal law that(every body attracts every other body with some force that is directly proportional to mass of the body and inversely proportional to the square of distance between there centers)
What is Rate of fall of temperature of the body is directly proportional to?
The rate of fall of temperature of the body is directly proportional to the temperature difference between the body and its surroundings, the surface area of the body exposed, and the thermal conductivity of the material between the body and its surroundings.
What does the gravitational force between the moon and earth depend on?
Their masses. The strength of a planetary body's gravitational field is directly related to its mass, and its effect on an object is inversely proportional to the square of the distance between the centers of the bodies.
What is velocity in physics class 9?
It is Distance travelled by body per unit of time
What is the difference between distance travelled by a body and its displacement and explain with a diagram?

A body travels a distance of 15m from A to B and then moves a distance of 20m at right angles to AB .Calculate the total distance traveled and the dispalecement?
Total distance travelled = 20m + 15m = 35m Total displacement travelled=20m - 15m =5m
How does the earths radius affect the gravitational force on a object at its surface?
The Earth and the object exert a gravitational force on each other, but only the Earth's is big enough to measure. So, the formula for gravitational force include the distance from one body's surface to its center and the same for the other body. The length of the radius is directly proportional to the body's gravitational force.
What does newtons 2nd law state?
Newtons 2nd law means that when force is applied on any object an acceleration is produced in the direction of force which is applied on it. The acceleration produced in the object is directly proportional to the force applied on the object i.e. if force increases then acceleration will also increase and the acceleration is inversely proportional to the mass of object i.e. if the mass of the body decreases then acceleration will increase. If force is represented by 'F', acceleration by 'a' and mass by 'm' then a is directly proportional to F a is inversely proportional to m
