The elastic properties of a spring depends on
both shape and the material of the spring
. … Elastic potential energy increases with the constant of the spring and with the distance stretched.
How does mass affect potential energy?
The amount of gravitational potential energy an object has depends on
its height and mass
. The heavier the object and the higher it is above the ground, the more gravitational potential energy it holds. Gravitational potential energy increases as weight and height increases.
Does elastic potential energy depend on mass?
Common types of potential energy include the gravitational potential energy of an object that depends on its
mass
and its distance from the center of mass of another object, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field.
Does mass affect speed?
The mass of an object does not change with speed
; it changes only if we cut off or add a piece to the object. … Since mass doesn’t change, when the kinetic energy of an object changes, its speed must be changing. Special Relativity (one of Einstein’s 1905 theories) deals with faster-moving objects.
What are 4 examples of potential energy?
- A raised weight.
- Water that is behind a dam.
- A car that is parked at the top of a hill.
- A yoyo before it is released.
- River water at the top of a waterfall.
- A book on a table before it falls.
- A child at the top of a slide.
- Ripe fruit before it falls.
Why does mass increase as speed increases?
As an object increases in speed, so
does the amount of energy that it has
, this energy is what we refer to as ‘the increase in mass’ (just remember, this is inertial mass). … Since an object has infinite kinetic energy when it approaches the speed of light, it therefore has infinite mass as well.
Does acceleration depend on mass?
The acceleration of an object depends
directly upon the net force acting upon the object
, and inversely upon the mass of the object. … As the mass of an object is increased, the acceleration of the object is decreased.
Does mass affect speed down a ramp?
Weight affects speed down the ramp
(the pull of gravity), but it’s the mass (and friction) that affects speed after a car leaves the ramp. Heavier cars have more momentum, so they travel further, given the same amount of friction.
What is the best example of potential energy?
An object can store energy as the result of its position. For example,
the heavy ball of a demolition machine
is storing energy when it is held at an elevated position. This stored energy of position is referred to as potential energy.
What are some examples of elastic potential energy?
- The coil spring of a wind-up clock.
- An archer’s stretched bow.
- A bent diving board, just before a divers jump.
- The twisted rubber band which powers a toy airplane.
- A bouncy ball, compressed at the moment it bounces off a brick wall.
What household items have potential energy?
- Pendulum. …
- Spring. …
- Bow & Arrow. …
- Rock At Cliff’s Edge. …
- Water In Dams & Reservoirs. …
- Rubber Band. …
- Wrecking Ball.
How does mass depend on speed?
As an object moves faster,
its mass increases
. (Note: this is true if “faster” is measured relative to an observer who is also the one measuring the mass. If the person measuring the mass is moving right along with the object, s/he will not observe any change in mass.)
Can anything travel faster than the speed of light?
Albert Einstein’s special theory of relativity famously dictates that
no known object can travel faster than the speed of light in vacuum
, which is 299,792 km/s. … Unlike objects within space–time, space–time itself can bend, expand or warp at any speed.
Do photons have mass?
Since photons (particles of light)
have no mass
, they must obey E = pc and therefore get all of their energy from their momentum. … But an object with zero energy and zero mass is nothing at all. Therefore, if an object with no mass is to physically exist, it can never be at rest. Such is the case with light.
Why does mass not 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.
Does more mass mean more acceleration?
Heavier things have a greater gravitational force
AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass.
