Step-by-step solution for: Newtons 3 Laws - Identification Worksheet | Science 10th Grade
Here is the completed Newton's 3 Laws Identification Worksheet with each scenario correctly identified and explained:
---
1. Sally rolls two balls, a heavy bowling ball and a light tennis ball. She notices that it is much easier to roll the tennis ball.
Newton’s Second Law
This demonstrates Newton’s Second Law (F = ma), which states that acceleration is inversely proportional to mass when force is constant. The tennis ball has less mass, so it accelerates more easily than the heavier bowling ball when the same force is applied.
---
2. A car slides out of control on ice.
Newton’s First Law
This illustrates Newton’s First Law (law of inertia): an object in motion stays in motion unless acted upon by an external force. On ice, friction is minimal, so the car continues moving in its original direction due to inertia until another force (like hitting something) stops it.
---
3. John notices that if he gives a box a harder push, it moves faster across the ground.
Newton’s Second Law
This reflects Newton’s Second Law: the greater the force applied, the greater the acceleration of an object (assuming mass remains constant). A harder push increases the net force, causing the box to accelerate more quickly.
---
4. Ashely notices that when she is paddling her kayak, she needs to push the water backwards to make her kayak go forwards which confuses her.
Newton’s Third Law
This shows Newton’s Third Law: for every action, there is an equal and opposite reaction. When Ashely pushes water backward with her paddle, the water pushes her kayak forward with an equal force.
---
5. A 35,000-pound truck needs a larger engine than a 2,000-pound car.
Newton’s Second Law
This relates to Newton’s Second Law because the truck has much greater mass and thus requires more force (provided by a larger engine) to achieve the same acceleration as the lighter car.
---
6. When Jasmine kicks a soccer ball, she notices that it travels along the ground but then stops.
Newton’s First Law
The ball continues moving after being kicked due to inertia (Newton’s First Law), but it eventually stops because of opposing forces like friction and air resistance acting against its motion.
---
7. Dwayne throws a ball down toward the ground. After it hits the ground, it bounces back up to him.
Newton’s Third Law
When the ball hits the ground, it exerts a downward force; the ground exerts an equal and opposite upward force, causing the ball to bounce back up—demonstrating action-reaction pairs.
---
8. To make a rocket go into the air, NASA engineers point it directly upwards prior to launch.
Newton’s Third Law
Rockets work based on Newton’s Third Law: the engines expel gas downward at high speed, and the gas pushes the rocket upward with an equal and opposite force.
---
9. Trisha notices that when playing tennis, the harder she swings her racquet, the faster the ball travels.
Newton’s Second Law
The harder Trisha swings (greater force), the greater the acceleration of the tennis ball, assuming its mass doesn’t change. This aligns with F = ma.
---
10. Kyle is driving a car that suddenly collides with the car in front. As the cars collided, Kyle kept moving forward but his seat belt kept him safe. It is lucky that Kyle was wearing his seat belt!
Newton’s First Law
Kyle continued moving forward due to inertia (Newton’s First Law)—his body wanted to keep moving at the original speed even when the car stopped abruptly. The seat belt provided the external force needed to stop him safely.
---
- First Law (Inertia): Objects resist changes in motion.
- Second Law (F = ma): Acceleration depends on net force and mass.
- Third Law (Action-Reaction): Every force has an equal and opposite reaction.
Each answer connects real-life situations to these fundamental physics principles.
