Answer:
1. In Physics, force is defined as: The push or pull on an object with mass causes it to change its velocity.
2. Contact forces are friction, tension, normal force, air resistance, and spring force. Non-contact forces are gravitational force, electric force, magnetic force, and electromagnetic force
3. In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
