Which of Newton's laws states that an object in motion stays in motion unless acted upon by an outside force?
Answer: First law (inertia)
Newton's first law, the law of inertia, describes objects resisting changes in motion.
What is the unit used to measure electric current?
Answer: Ampere
Electric current is measured in amperes, often shortened to amps.
When two objects rub together, which force opposes their motion?
Answer: Friction
Friction is the force that resists motion between two surfaces in contact.
Energy stored in an object due to its position or height is called what?
Answer: Potential energy
Potential energy is stored energy based on an object's position, such as height.
According to Newton's second law, if mass stays the same and force increases, acceleration will do what?
Answer: Increase
Since F=ma, a greater force on the same mass produces greater acceleration.
What form of energy travels in waves and allows us to see objects?
Answer: Light energy
Light energy is electromagnetic radiation that the eyes detect to enable vision.
For every action force, there is an equal and opposite reaction force. This describes which law?
Answer: Newton's third law
Newton's third law states that forces come in equal and opposite pairs.
