WebQuest: Kinematic - Kinematics: Horizontal Motion

Kinematics is the study of:

• motion of objects without considering its causes

• forces acting on objects

• energy transformations

• properties of matter

Kinematic equations do which of the following?

• Describe the motion of objects using variables like displacement, velocity, and acceleration.

• Explain the chemical properties of substances.

• Predict the outcome of genetic crosses.

• Measure the temperature of a system.

Which of the following lists the kinematic 5 variables and their meanings correctly?

• Displacement (Δx), Initial velocity (v₀), Final velocity (v), Acceleration (a), Time (t)

• Force (F), Mass (m), Power (P), Energy (E), Work (W)

• Distance (d), Speed (s), Momentum (p), Impulse (J), Pressure (P)

• Velocity (v), Frequency (f), Wavelength (λ), Amplitude (A), Period (T)

4. ____________________________________________ will always have a constant value.

• Acceleration will always have a constant value.

• Velocity will always have a constant value.

• Distance will always have a constant value.

• Time will always have a constant value.

What is another variable used to represent horizontal displacement?

• x

• y

• t

• v

The purpose of kinematic equations is to:

• Describe the motion of objects using relationships between displacement, velocity, acceleration, and time.

• Explain the causes of motion based on forces.

• Calculate the energy of moving objects.

• Determine the mass of an object in motion.

The correct sequence of steps to solve kinematic problems is:

• Identify known and unknown variables, choose the appropriate kinematic equation, solve for the unknown, and check your answer.

• Guess the answer, check the textbook, and write any equation.

• Draw a random diagram, use any formula, and write the answer.

• Memorize all equations and use them without checking variables.

Three important pieces of information to write out prior to solving any problems are:

• The given information, what is being asked, and the formula or method to use.

• The answer, the teacher's name, and the date.

• The textbook page number, the color of your pen, and your favorite subject.

• The time of day, the weather, and your friend's name.

Free fall is:

• the motion of an object under the influence of gravity only

• the motion of an object with air resistance

• the motion of an object on a flat surface

• the motion of an object in water

When an object is in free fall on Earth, what value of acceleration does it experience?

• 9.8 m/s²

• 0 m/s²

• 1.6 m/s²

• 4.9 m/s²
