Answer. When the skater’s mass increased, he had higher kinetic and potential energy as he went up and down the ramp. His total energy increased too. An increase in mass comes with an increase in kinetic and potential energy.
How does mass affect the speed of the skater?
This is Newton’s Second Law – force on an object produces acceleration. The greater the mass, the sum of all matter in the skater’s body and equipment, the more force he must generate to accelerate down the track.
Does changing the mass affect the speed of the skater Why or why not?
Actually, mass does not affect velocity. Moving with 100 km/hr has got nothing to do with the object being 1 kg or 100 kg.
What happened to the energy of the skater as he moved up and down the ramp?
The skater’s kinetic energy decreases as he moves up the ramp. As the skater moves down the ramp, his potential energy decreases.
What happens to the total energy of the skater when height decreases?
The total energy does not change and is only determined by the initial height of the skater when dropped on the track. 19. Over time, the thermal energy in the track will dissipate.
Why does speed decrease when mass increases?
The velocity would decrease because mass and velocity are inversely related. The equation for Kinetic Energy is: KE = 1/2 mv2. Kinetic energy has a direct relationship with mass, meaning that as mass increases so does the Kinetic Energy of an object. The same is true of velocity.
Why does changing the mass affect the speed?
Mass doesn’t affect speed directly. It determines how quickly an object can change speed (accelerate) under the action of a given force. Lighter objects need less time to change speed by a given amount under a given force.
Why does mass not affect the speed of a falling object?
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.
Why mass does not affect free fall?
The acceleration of the object equals the gravitational acceleration. The mass, size, and shape of the object are not a factor in describing the motion of the object. So all objects, regardless of size or shape or weight, free fall with the same acceleration.
How does the mass of an object affect the distance it travels?
Mass does not affect either velocity, time, or distance.
When a skateboarder skates down a ramp she speeds up which increases her kinetic energy where does that extra energy come from?
Gravitational potential energy gets converted to kinetic energy as the skater goes down one side of the ramp, then gets converted back to gravitational potential energy as they go up the other side.
Do you think a moving skateboard has energy Why or why not?
So, does a moving skateboard have energy? Yes. It’s kinetic energy, the one found in objects in motion. Otherwise, it’s potential energy.
How does gravitational potential energy change as the skateboarder goes up and down explain?
As the skateboarder moves, her potential energy is converted to kinetic energy (KE), or the energy of motion as her position changes along the track and the velocity changes. The maximum amount of kinetic energy the skateboarder can have is entirely dependent on the amount of potential energy of the system.
Does mass affect the amount of energy?
Mass and kinetic energy have a positive relationship, which means that as mass increases, kinetic energy increases, if all other factors are held constant.
When the ball descends which energy decreases and which energy remains the same?
The total energy of the ball remains the same. At maximum height, the velocity is zero (no kinetic energy) and the ball will have only potential energy. The energy possessed by a body by virtue of its position is called potential energy. The energy possessed by a body due to its motion is called kinetic energy.
Why is there a slight decrease in the total energy near the end of the run?
Friction and air resistance are both external forces and would do work upon the moving object. In fact, the presence of friction and air resistance would do negative work and cause the total mechanical energy to decrease during the course of the motion.
Why does mass increase the faster you go?
That’s called kinetic energy, energy of motion. So E equals MC squared, now your mass has not just the stuff that’s in you but also the energy of your motion. And that’s why mass seems to increase as you go faster, and faster, and closer to the speed of light.
Does mass increase or decrease with 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.)
What happens when mass increases?
Therefore when you increase the mass the number of an atom in your system also increases. This also affects physical value such as force if the acceleration has remained constant increasing the mass will increase the force that is to be exerted on the object in order to maintain its acceleration.
How does increasing mass affect the force of object in motion?
The greater the mass the greater the amount of force needed to accelerate the object. More force is required to move a heavier object than a lighter object.
Does the mass of an object affect how fast it falls?
Mass does not affect the speed of falling objects, assuming there is only gravity acting on it.
