Newton's first law of motion states that an object's motion will not change unless

• the net force acting on it is greater than zero

• a force continues to be applied

• its inertia is stronger than the applied force

• the object has no inertia

What is mass and what does it depend on?

• Mass is the weight of the object, it depends on the gravitational force acting on the object

• Mass is the weight of the object, it depends on the number and types of atoms in the object

• Mass is the quantity of matter in an object and depends on the gravitational force acting on it

• Mass is the quantity of matter in an object, and depends on the number and types of atoms in the object

If the net force acting on two different objects is the same, how does the acceleration of the object change in relation to its mass?

• acceleration is directly proportional to its mass

• acceleration is inversely proportional to its mass

• acceleration is not affected by mass

• acceleration is directly proportional to the square of the mass
