1. In physics, what is a system?
A group of objects
A system is a group of objects that interact through forces or energy transfer.
2. Which store is used when you stretch a spring?
Elastic potential
Stretching a spring stores energy in its elastic potential store.
3. What store increases as a ball is thrown up?
Gravitational
Work done against gravity transfers kinetic energy into gravitational potential.
4. Which store increases when an object speeds up?
Kinetic
Kinetic energy depends on the mass and the square of the speed.
5. When an object hits a wall, its energy mostly becomes:
Sound and thermal
Most kinetic energy dissipates as sound and thermal energy on impact.
6. What happens to energy in a closed system?
It is conserved
Energy cannot be created or destroyed — it is conserved, only transferred.
