What is the primary use of kinematic equations in physics?

• To describe the motion of objects using mathematical relationships

• To calculate the mass of an object

• To determine the chemical composition of a substance

• To measure the temperature of an object

Which of the following is NOT a parameter involved in kinematic equations?

• Displacement

• Velocity

• Acceleration

• Mass

If a car accelerates from rest with an acceleration of 3.0 m/s² east for 8.0 seconds, what is its final velocity?

• 24 m/s east

• 22 m/s east

• 20 m/s east

• 26 m/s east

Which kinematic equation would you use to find displacement when the final velocity is not known?

• Δx = v₀t + 1/2 at²

• v = v₀ + at

• Δx = (v + v₀)/2 * t

• v² = v₀² + 2aΔx

What is the first step in solving a kinematics problem according to the passage?

• Identify the known values and their corresponding symbols

• Select the appropriate kinematic equation

• Substitute the known values into the equation

• Determine the goal of the problem
