Exploring Constant Acceleration in Motion Equations

What is the basic equation for position when starting from the origin?

• Position = Velocity + Time

• Position = Time / Velocity

• Position = Velocity / Time

• Position = Velocity * Time

Why does the equation 'Position = Velocity * Time' make sense in terms of units?

• Because time equals velocity

• Because meters per second equals meters

• Because seconds equals seconds

• Because meters equals meters

How do you modify the position equation to include a non-zero initial position?

• Add the initial position to the product of velocity and time

• Multiply the initial position by the product of velocity and time

• Subtract the initial position from the product of velocity and time

• Divide the initial position by the product of velocity and time

What does the slope of the position-time graph represent?

• Position

• Velocity

• Acceleration

• Time

What is the effect of acceleration on velocity?

• It has no effect on velocity

• It decreases the velocity

• It keeps the velocity constant

• It changes the velocity over time

What does the area under the velocity-time graph represent?

• Acceleration

• Time

• Velocity

• Displacement

How do you calculate the area of the rectangle under the velocity-time graph?

• Initial position times time

• Initial velocity times time

• Final velocity times time

• Acceleration times time

What is the formula for the area of a triangle under the velocity-time graph?

• Base + height

• 1/3 * base * height

• Base * height

• 1/2 * base * height

What is the final formula for position that includes initial velocity and acceleration?

• Position = Initial velocity + Acceleration * Time

• Position = Initial velocity * Time + 1/2 * Acceleration * Time^2

• Position = Initial velocity / Time + 1/2 * Acceleration * Time^2

• Position = Initial velocity * Time - 1/2 * Acceleration * Time^2
