Displacement and Acceleration

How do you calculate displacement?

• Displacement = Final position / Initial position

• Displacement = Final position - Initial position

• Displacement = Final position + Initial position

• Displacement = Final position x Initial position

What is the acceleration due to gravity on Earth?

• 10.25 m/s^2

• 8.91 m/s^2

• 9.81 m/s^2

• 6.67 m/s^2

How can you represent acceleration vs. time graphically?

• Plot time on the y-axis and acceleration on the x-axis

• Represent acceleration vs. time using a scatter plot

• Use a pie chart to represent acceleration vs. time

• Plot acceleration on the y-axis and time on the x-axis

If an object is moving with a constant velocity, what can you say about its acceleration?

• Acceleration is increasing

• Acceleration is constant

• Acceleration is negative

• Acceleration is zero.

Calculate the displacement if an object moves 5 meters to the right and then 3 meters to the left.

• 2 meters to the right

• 1 meter to the left

• 8 meters to the right

• 5 meters to the left

What is the formula to calculate acceleration?

• acceleration = (final velocity - initial velocity) * time

• acceleration = (final velocity * initial velocity) / time

• acceleration = (final velocity - initial velocity) / time

• acceleration = (final velocity + initial velocity) / time

What is the value of acceleration due to gravity in m/s^2?

• 10.05

• 7.62

• 8.91

• 9.81

Describe the motion of an object with a positive acceleration.

• The object is moving in the opposite direction of its velocity

• The object is moving in the direction of its velocity, and its speed is increasing.

• The object is decelerating

• The object is at rest

A car is accelerating at 2 m/s^2. How much will its velocity change in 5 seconds?

• 10 m/s

• 25 m/s

• 20 m/s

• 15 m/s

Explain the difference between speed and velocity.

• Velocity is a scalar quantity.

• Speed is a vector quantity.

• Speed is the magnitude of velocity.

• Velocity is the rate of change of position.
