Motion
What is the unit for speed
m/s
What is the unit of force
Newton
What is kinetic energy
Energy an object has due to its motion
If a car travels 60 in 2 hours, what is it's speed
30km/hr
What does newton third law states
For every action there is an equal and opposite reaction
What energy conversion happens in a toaster
Electrical energy to heat energy
What happens to potential energy when an object falls
Potential energy is the energy stored due to an object's height above the ground.
As the object falls, it loses height.
The lost potential energy is transformed into kinetic energy (the energy of motion).
The total energy stays the same (law of conservation of energy), but it changes form
If a 2 kg object accelerates at 3 m/s², what is the force acting on it?
