Understanding the Context of LivePhoto Physics Activity 16

Before diving into the solutions, it’s vital to understand what Activity 16 involves. Typically, this activity is part of a series designed to help students analyze various physical phenomena through experiments or problem-solving exercises.

Goals of Activity 16

• Analyze the motion of objects under different conditions.
• Calculate quantities such as velocity, acceleration, and displacement.
• Understand the relationship between force, mass, and acceleration.
• Develop problem-solving skills related to kinematics and dynamics.

Common Questions and Detailed Answers from Activity 16

Below, we present a comprehensive overview of typical questions from Activity 16 along with step-by-step solutions and explanations.

Question 1: How to determine the velocity of an object moving in a straight line?

The velocity of an object moving in a straight line can be calculated using the formula:

v = s / t

where:

• v = velocity (m/s)
• s = displacement or distance traveled (m)
• t = time taken (s)

Example: If a car travels 150 meters in 30 seconds, its velocity is:

v = 150 / 30 = 5 m/s

Question 2: How to calculate acceleration when initial and final velocities are known?

Acceleration can be calculated using the formula:

a = (vf - vi) / t

where:

• a = acceleration (m/s²)
• v_f = final velocity (m/s)
• v_i = initial velocity (m/s)
• t = time taken (s)

Example: If an object accelerates from 10 m/s to 20 m/s in 5 seconds, then:

a = (20 - 10) / 5 = 2 m/s2

Question 3: What is the significance of free fall in physics activity?

Free fall refers to the motion of an object under the influence of gravity alone, neglecting air resistance. The acceleration due to gravity (g) is approximately 9.8 m/s² on Earth. Analyzing free fall helps students understand concepts of acceleration, velocity change over time, and gravitational potential energy.

Question 4: How do we calculate the time of fall for an object dropped from a certain height?

The time of fall (t) can be found using the equation:

h = (1/2) g t2

Rearranged as:

t = √(2h / g)

where:

• h = height (m)
• g = acceleration due to gravity (9.8 m/s²)

Example: Dropping an object from 45 meters:

t = √(2  45 / 9.8) ≈ √(9.18) ≈ 3.03 seconds

Question 5: How to analyze the motion of a projectile launched at an angle?

Projectile motion involves two components: horizontal and vertical.

1. Horizontal motion: constant velocity, no acceleration (ignoring air resistance).
2. Vertical motion: uniformly accelerated motion under gravity.

Key formulas:

• Horizontal displacement: s_x = v_x t
• Vertical displacement: s_y = v_y t - (1/2) g t²

where initial velocities are broken into components:

vx = v0 cos θ, vy = v0 sin θ

Step-by-Step Solutions for Key Problems

This section provides detailed solutions to sample problems from Activity 16, ensuring clarity and understanding.

Sample Problem 1: Calculating Final Velocity in Uniform Acceleration

Question: An object starting from rest accelerates uniformly at 3 m/s² for 8 seconds. What is its final velocity?

Solution:

• Initial velocity, v_i = 0 m/s
• Acceleration, a = 3 m/s²
• Time, t = 8 s

Using the formula:

vf = vi + a t = 0 + (3)(8) = 24 m/s

Answer: The final velocity is 24 m/s.

Sample Problem 2: Determining Distance Traveled During Uniform Acceleration

Question: Using the previous problem, what is the displacement after 8 seconds?

Solution:

Using the equation:

s = vi t + (1/2) a t2

s = 0  8 + 0.5  3  82 = 0 + 0.5  3  64 = 96 meters

Answer: The object travels 96 meters in 8 seconds.

Detailed Breakdown of Typical Questions and Answers

Question 1: Calculating Velocity from a LivePhoto

Question:

A student captures a photo of a ball rolling down a ramp. The photo indicates the ball traveled 2 meters in 4 seconds. What is the average velocity of the ball?

Answer:

The average velocity \( v_{avg} \) is calculated as total displacement divided by total time:

\[

v_{avg} = \frac{\text{displacement}}{\text{time}} = \frac{2\, \text{m}}{4\, \text{s}} = 0.5\, \text{m/s}

\]

Analysis:

This straightforward calculation introduces students to the concept of average velocity, emphasizing the importance of units and understanding that velocity includes direction, although in this case, the movement is likely along a straight path.

Question 2: Determining Acceleration Using Multiple Positions

Question:

Given three positions of a moving object captured in a LivePhoto at times t1, t2, and t3, how can you determine the acceleration?

Answer:

To find acceleration:

1. Calculate velocities between positions:

\[

v_1 = \frac{\text{position}_2 - \text{position}_1}{t_2 - t_1}

\]

\[

v_2 = \frac{\text{position}_3 - \text{position}_2}{t_3 - t_2}

\]

2. Then, compute acceleration:

\[

a = \frac{v_2 - v_1}{t_3 - t_1}

\]

Analysis:

This approach demonstrates how to derive acceleration from discrete position data, reinforcing the relationship between position, velocity, and acceleration. It also highlights the importance of choosing consistent time intervals and units.

Question 3: Applying Newton's Second Law

Question:

A 2 kg object experiences a net force of 10 N. What is its acceleration?

Answer:

Using Newton’s Second Law:

\[

F_{net} = m \times a

\]

\[

a = \frac{F_{net}}{m} = \frac{10\, \text{N}}{2\, \text{kg}} = 5\, \text{m/s}^2

\]

Analysis:

This exemplifies the direct application of Newton's law, emphasizing the importance of correctly identifying mass and net force.

Question 4: Energy Conservation in a LivePhoto Scenario

Question:

A ball rolls down a hill, converting potential energy into kinetic energy. If the initial height is 5 meters and the mass of the ball is 0.5 kg, what is its velocity at the bottom?

Answer:

Potential energy at the top:

\[

PE = m \times g \times h = 0.5\, \text{kg} \times 9.8\, \text{m/s}^2 \times 5\, \text{m} = 24.5\, \text{J}

\]

Assuming no energy losses, kinetic energy at the bottom:

\[

KE = PE = 24.5\, \text{J}

\]

Velocity at the bottom:

\[

KE = \frac{1}{2} m v^2 \Rightarrow v = \sqrt{\frac{2 KE}{m}} = \sqrt{\frac{2 \times 24.5}{0.5}} = \sqrt{98} \approx 9.9\, \text{m/s}

\]

Analysis:

This problem reinforces the conservation of energy principle and illustrates how to compute velocity from energy considerations.

Question 5: Analyzing Projectile Motion

Question:

A ball is projected horizontally from a height of 3 meters with an initial speed of 4 m/s. How far does it travel horizontally before hitting the ground?

Answer:

1. Time to fall:

\[

t = \sqrt{\frac{2h}{g}} = \sqrt{\frac{2 \times 3\, \text{m}}{9.8\, \text{m/s}^2}} \approx 0.78\, \text{s}

\]

2. Horizontal distance:

\[

d = v_{initial} \times t = 4\, \text{m/s} \times 0.78\, \text{s} \approx 3.12\, \text{m}

\]

Analysis:

This demonstrates the independence of horizontal and vertical motions in projectile physics, a crucial concept in understanding real-world projectile behavior.
