What happened to the combined energy of the two sleds when they collided? E.
Because energy is conserved, the “lost” energy has actually been changed into other forms
.
Is energy conserved in a sled collision?
Because
momentum is conserved
, the sled keeps the same speed. Momentum is conserved in all collisions. Collisions in which kinetic energy is conserved as well are called elastic collisions, and those in which it is not are called inelastic.

.
What is the kinetic energy of sled B after the collision?
When they collide, they bounce off each other and no energy is lost. The kinetic energy of sled A is
39,561 J
just after the collision.
What is the potential energy of each sled which sled do you think will push the other back when they collide explain?
Which sled do you think will push the other back when they collide? The
red sled should push the blue sled back
. Explain. The red sled, with its greater mass should have a higher momentum than the blue sled, which would allow it to push back on the blue sled once they collide.
How does increasing the starting height affect the final speed?
Does the mass of the sled effect the final speed? the height of the starting point will increase the final speed. … it increases, one its at
a higher point
and with more mass more energy can be stored.
Is momentum conserved in a collision with a wall?
When it hits a vertical wall it rebounds with a horizontal velocity v to the left. Since momentum is mass times velocity there would be a tendency to say
momentum has been conserved
.
What type of collision is a car crash?
Some of the kinetic energy is converted into sound, heat, and deformation of the objects. A high speed car collision is an
inelastic collision
.
How Does height affect total energy?
2. At an object’s maximum height, kinetic energy is zero/ maximum while the potential energy is zero/ maximum. 3. … As an object falls under the influence of gravity,
total energy increases / decreases
/ remains the same.
How does doubling height affect potential energy?
Since the gravitational potential energy of an object is directly proportional to its
height
above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy.
What is the connection between work and energy?
The relationship between work and Kinetic Energy, also called the Work-Energy theorem, states that
the work done by the sum of all the force acting over any particle/ object is equal to the change in the Kinetic Energy of the particle.
What factors affect the speed of the sled?
The angle of the hill’s incline, the distance that the incline continues, and the friction between your sled and the snow
will affect maximum speed.
Does the mass of the sled affect its final speed?
Does the mass of the sled affect its final speed? In this Gizmo, there is no friction, so there is no force slowing the sled down. As long as there is no friction, the sled’s final speed only depends on the starting height. In the
real world, friction will affect the sled’s final speed
.
What is true about the momentum of the winning sled?
What is true about the momentum of the winning sled in each contest?
It is Always greater than other sled B
. If you knew each sled’s mass and speed, how could you determine which sled will be pushed backward in a collision?
How does potential energy change when mass is increased?
Gravitational potential energy may be converted to other forms of energy, such as kinetic energy. If we release the mass, gravitational force
will do an amount of work equal to mgh on it
, thereby increasing its kinetic energy by that same amount (by the work-energy theorem).
What happens to the amounts of potential and kinetic energy as the sled goes down the hill what happens to the total energy?
As I stand with my sled at the top of the hill, the kinetic energy is zero and the potential energy is at its maximum. As I slide down the hill,
the potential energy of the sled decreases and its kinetic energy increases
.
