How does the height of a ramp affect acceleration?
A: If you increase the steepness of the ramp, then you will increase the acceleration of a ball which rolls down the ramp.
If the ramp is horizontal, then the ball does not accelerate, as gravity pushes the ball into the ramp and not along the surface of the ramp..
What factors affect acceleration due to gravity?
The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases.
At what height gravity is zero?
Near the surface of the Earth (sea level), gravity decreases with height such that linear extrapolation would give zero gravity at a height of one half of the Earth’s radius – (9.8 m. s−2 per 3,200 km.)
Why is G universal constant?
The value of G does not depend on the nature of the intervening medium. Also, G is constant for any object in the universe. Hence, is is known as ‘universal gravitational constant’.
How does distance affect time?
distance does relate to time though. two objects going the same velocity but different distances require a different amount of time to complete. … this is because the velocity of an object is figured out by distance traveled being compared to a unit of time.
Does distance affect speed?
How does distance affect speed? The speed is directly proportional to distance travelled. The definition says,the measure of speed is distance travelled by a body of uniform mass per unit time henceforth,speed is directly proportional to the distance travelled by the body.
Does slope affect acceleration?
As the angle increases, the component of force parallel to the incline increases and the component of force perpendicular to the incline decreases. It is the parallel component of the weight vector that causes the acceleration. Thus, accelerations are greater at greater angles of incline.
How does steepness affect acceleration?
If you increase the steepness of the ramp, then you will increase the acceleration of a ball which rolls down the ramp. This can be seen in two different ways: 1) Components of forces. … Therefore, only the component of the gravitational force which points along the direction of the ball’s motion can accelerate the ball.
Where is acceleration due to gravity is maximum?
The acceleration due to gravity on the earth surface will be maximum at poles and minimum at equator. Radius of the equator is greater than the radius of the pole. Since gravity is inversely proportional to the radius the net gravity at equator is less than the gravity at the pole.
Why does acceleration due to gravity decrease with height?
Acceleration due to gravity decreases with altitude because the attractive force of gravity decreases with altitude. The force of gravitational attraction is defined by the formula , where G is the gravitational constant, , and are the masses of the two bodies, and r is the center-to-center distance between them.
Where is gravity strongest on earth?
In the case of the earth, the force of gravity is greatest on its surface and gradually decreases as you move away from its centre (as a square of the distance between the object and the center of the Earth).
Does gravity affect acceleration?
When objects fall to the ground, gravity causes them to accelerate. … Gravity causes an object to fall toward the ground at a faster and faster velocity the longer the object falls. In fact, its velocity increases by 9.8 m/s2, so by 1 second after an object starts falling, its velocity is 9.8 m/s.
What is the acceleration of free fall?
It was learned in the previous part of this lesson that a free-falling object is an object that is falling under the sole influence of gravity. A free-falling object has an acceleration of 9.8 m/s/s, downward (on Earth). … The numerical value for the acceleration of gravity is most accurately known as 9.8 m/s/s.
Does acceleration due to gravity increase with height?
For an object placed at a height h, the acceleration due to gravity is less as compared to that placed on the surface. As depth increases, the value of acceleration due to gravity (g) falls. The value of g is more at equator and less at poles.
Why is gravity 9.81 ms 2?
“9.81 meters per second squared” means that objects on Earth will accelerate (or go faster) 9.81 meters every second, if they are in free fall, due to the pull of gravity. … It is the acceleration due to gravity that changes and that is what we are talking about when we say gravity is 9.81 meters per second squared.
Does mass affect acceleration?
“What are the factors that affect the acceleration due to gravity?” Mass does not affect the acceleration due to gravity in any measurable way. The two quantities are independent of one another. Light objects accelerate more slowly than heavy objects only when forces other than gravity are also at work.
How is speed calculated?
The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in metres (m) and time is in seconds (s), so the units will be in metres per second (m/s).
Does weight affect stopping distance?
The weight of a car does affect its braking distance. The greater the mass of an object, the greater its inertia (tendency to stay moving once moving in this case). If you are comparing some heavier models that stop in less disatance than a lighter car, this is because the car is engineered to do so.
