Best answer gets BRAINLIEST 1. Explain why high speed collision between two cars would cause more damage than a low speed collision between the same two cars.
2. Describe the energy transformations that occur when a piece of wood
is burned.
3. Identify the form of energy that is converted into thermal energy.
5. Think critically A golf ball and a bowling ball are moving and both have the same kinetic energy. Which one is moving faster? If they move at the same speed, which one has more kinetic energy?

ch1. The more mass and speed and object has, the greater its kinetic energy. ... At lower speeds, the kinetic energy is less, so the impact would be less and there would be less damage.

or

Damages in collisions of two cars are caused by forces. These forces area called impulse forces or the change in momentum of the cars in a very short time interval.

Momentum P = MV where M is the mass of the car. The mass of the car does not change if we consider the same car moving at high-speed and if it collides with another moving or stationary object, it will have a higher change in momentum compare to moving at a lower speed. If the changes in the momentum occur in a short time interval Δt, the impulse of force generated (F =ΔP/Δt) at high speed is greater than that produced at low speed. This force will cause more damages for high-speed collision compare to low-speed collision.

2. In the case of burning wood, stored potential energy (in the form of chemical energy) in the log is released due to heating by other excited atoms. This chemical reaction is called combustion and requires oxygen. Combustion changes the potential chemical energy into kinetic energy in the form of heat .

3. chemical potential energy in our body or just potential energy simply

4. lol they can't have same kinetic energy, cuz we know bowling ball has greater mass and too it mentioned here " which one is moving faster " ! if they would move at the same speed, the bowling ball would have more kinetic energy because of it's greater mass

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.
