Physics Concepts acceleration Quiz

How can you calculate average velocity?

• Total displacement divided by total time taken

• Total displacement divided by total distance traveled.

• Total displacement multiplied by total time taken.

• Total distance divided by total time taken.

What do distance vs time graphs represent?

• The relationship between distance traveled and the time taken to travel that distance.

• The speed at which an object is traveling.

• The acceleration of an object.

• The direction an object is moving in.

What does a straight line in a distance vs time graph represent?

• A straight line represents constant acceleration.

• A straight line represents constant speed.

• A straight line represents constant time.

• A straight line represents constant displacement.

What does the slope of a velocity vs time graph represent?

• The acceleration of the object.

• The distance covered by the object.

• The speed of the object.

• The time taken by the object.

What is the formula for calculating acceleration?

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

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

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

• acceleration = final velocity / time

How can you calculate acceleration using time and change in velocity?

• Acceleration = Time * Change in velocity.

• Acceleration = Time + Change in velocity.

• Acceleration = Change in velocity / Time

• Acceleration = Time / Change in velocity.
