Vocabulary
- Newton’s Second Law of Motion — A relationship describing how force, mass, and acceleration are related.
- Force — An influence that causes an object to undergo a change in speed, direction, or shape.
- Mass — A measure of the amount of matter in an object, influencing its inertia.
- Acceleration — The rate at which an object’s velocity changes over time.
- Unbalanced Force — A net force acting on an object that causes it to accelerate.
Questions
Watch the video carefully and answer the following questions based on the information presented.
1.
At 0:25, the video asks what force or forces are acting on a ball thrown upwards after it leaves your hand, neglecting air resistance. What is the correct answer, and why?
2.
According to the video (1:28), what three distinct changes can occur to an object’s motion when it is subjected to an unbalanced force?
3.
The video (4:24) uses the example of throwing a tennis ball versus a shot put. Explain why a tennis ball can be thrown much faster than a shot put, based on the principles discussed in the video.
4.
In the race car example (3:23), a car with a mass of 1200 kg has an engine producing a constant force of 3400 N, and a constant frictional force of 400 N acts on it. What is the resultant force acting on the car?
5.
Newton’s Second Law of Motion, , describes the relationship between force, mass, and acceleration. Choose one of the calculation examples from the video (spacecraft, car, toy car, or object mass) and discuss how altering one of the variables would impact another, assuming the third remains constant. For instance, if the mass of the object in your chosen example were doubled, how would that affect its acceleration if the force remained the same?
