Answer in one word/ sentence
1. What is velocity?
2. What is Newton's laws?
3. Define gravitational mass?
4. What is conservation of energy?
Please give me answer quickly.
Answers
Explanation:
1. the speed of something in a given direction is called velocity
2.Newton's laws of motion are three laws that describe the relationship between the motion of an object and the forces acting on it. The first law states that an object either remains at rest or continues to move at a constant velocity, unless it is acted upon by an external force.
3. Gravitational mass is determined by the strength of the gravitational force experienced by the body when in the gravitational field g. The Eötvös experiments therefore show that the ratio of gravitational and inertial mass is the same for different substances.
4. Conservation of energy, principle of physics according to which the energy of interacting bodies or particles in a closed system remains constant. The first kind of energy to be recognized was kinetic energy, or energy of motion.
Answer:
1) the speed at which something moves in a particular direction
