What is the effect of applying an unbalanced force on an object?
The object accelerates (changes its velocity).
What is the effect of an object having a large inertial mass?
It is harder to accelerate the object.
What happens when the net force acting on an object is zero?
The object remains at rest or continues to move at a constant velocity.
What are the steps to experimentally determine the relationship between net force, inertial mass, and acceleration?
- Measure mass. 2. Apply varying forces. 3. Measure acceleration. 4. Record data. 5. Plot force vs. acceleration. 6. Examine the relationship.
What are the steps to measure gravitational mass of a golf ball using a balance scale?
- Place the golf ball on one side of the balance. 2. Place known masses on the other side until balanced. 3. The known masses will equal the gravitational mass of the golf ball.
What are the steps to measure inertial mass of a golf ball using a force sensor, track, timer, and photogate?
- Apply a known force to the golf ball. 2. Measure its acceleration. 3. Use Newton's Second Law () to calculate inertial mass ().
What are the key differences between gravitational mass and inertial mass?
Gravitational Mass: Determined by gravitational attraction. | Inertial Mass: Determined by resistance to changes in motion.
Differentiate between mass and weight.
Mass: A measure of inertia (how hard it is to accelerate something). | Weight: The force of gravity on an object ().
