If a spring is fully loaded and up against a cart, what kind of energy does it have August
potential energy
how do other contact forces from interactions(with the air and the track) cuase energy transfers in the luancher system august
Friction and air resistance slow it down
What happens to kinetic energy when mass doubles but speed stays the same?
The kinetic energy doubles.
When two objects collide, why don’t they always move the same distance afterward?
Because their masses are different, and heavier objects accelerate less from the same force.
How does changing the mass or speed of an object affect the forces on the object during a collision? rylin
Changing speed more dramatically affects the amount of force
It came from the spring and went to the track
A contact force going against motion that causes resistance.
What happens to kinetic energy when speed doubles but mass stays the same?
The kinetic energy quadruples (it increases four times).
What would happen if the same object hit two targets made of different materials?
The softer material would deform more, absorbing energy and reducing force on the object.
How much does doubling the mass of an object affect its Ke and damage Rylin
the ke doubles
What is fragile
Something that can be easily broken/damaged
Why is speed a bigger factor than mass in collision damage?
Because energy depends on speed squared, so small increases in speed cause large increases in energy.
How do equal and opposite forces explain why both objects change motion in a collision?
Each object pushes on the other with the same strength but in opposite directions, causing both to move or deform.
How much does doubling the speed of an object affect its Ke and damage August
changes it without an even rate
What is elasticity
How easly an object can return to its original shape after being disformed
How does increasing the mass of a moving object affect the collision?
It increases the force during the collision since heavier objects are harder to stop.
Why does a small increase in speed cause a large increase in collision energy?
Because kinetic energy grows with the square of speed, not just in a straight line.
Where did the energy in the launcher system come from and after the system, where did it go. jj
It came from the spring and went to the track
if a large fast cart collides with a small slow cart which will experience more force
neither it is the same
What happens to the collision forces when the speed of an object increases?
The forces get stronger because a faster object has more momentum and energy.
Why does a heavier object usually cause a stronger collision?
Because it has more momentum, which means it resists changes in motion more.
