Question

drag and drop the words or phrases that accurately complete the paragraph. a force is defined as the push or pull on an object with mass that causes it to change velocity (the speed of something in a given direction). all forces can be classified into two types of forces: a force that requires physical contact with an object to occur is called a □ force. a force that acts over a distance is called a □ force. forces are represented by the equation: force = □ × acceleration. non - contact law density contact mass gravity

Explanation:

1. For the first blank: A force requiring physical contact is a "contact" force (since contact forces need direct touch, like friction or normal force).
2. For the second blank: A force acting over distance (no direct contact, like gravity, magnetism) is "non - contact".
3. For the third blank: The formula for force is \( F = m\times a \) (Newton's second law), so the missing term is "mass".

Answer:

First blank: contact
Second blank: non - contact
Third blank: mass
