Motion Concepts

What is the formula for speed?

• Speed = Distance x Time

• Speed = Time / Distance

• Speed = Distance + Time

• Speed = Distance / Time

Define acceleration.

• Acceleration is the rate of change of velocity with respect to time.

• Acceleration is the distance traveled divided by the time taken.

• Acceleration is the force acting on an object.

• Acceleration is the speed of an object.

How is acceleration calculated?

• acceleration = final velocity / time

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

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

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

Explain the concept of distance-time graphs.

• Distance-time graphs are used to measure weight and distance

• Distance-time graphs illustrate the relationship between distance and time for an object's motion.

• Distance-time graphs show the relationship between speed and time

• Distance-time graphs are only applicable to stationary objects

What does a horizontal line on a distance-time graph represent?

• Object decelerating

• Object in motion

• Object at rest

• Object accelerating

Describe the slope of a distance-time graph.

• The slope of a distance-time graph represents the color of the object.

• The slope of a distance-time graph represents the speed or velocity of an object.

• The slope of a distance-time graph represents the temperature of the object.

• The slope of a distance-time graph represents the weight of the object.

What information does a velocity-time graph provide?

• It displays the weight of an object

• It indicates the temperature of the environment

• It reveals the color of the object

• It shows the acceleration, deceleration, constant velocity, and direction of motion of an object.

How is velocity calculated from a velocity-time graph?

• Velocity is calculated by finding the maximum value on the velocity-time graph.

• Velocity is calculated by finding the area under the velocity-time graph.

• Velocity is calculated by finding the y-intercept of the velocity-time graph.

• Velocity is calculated by finding the slope of the velocity-time graph.

What does a horizontal line on a velocity-time graph indicate?

• Acceleration

• Decreasing velocity

• Increasing velocity

• Constant velocity

Differentiate between speed and velocity.

• Speed and velocity are the same thing.

• Speed is scalar, velocity is vector.

• Speed is a vector, velocity is scalar.

• Speed is a measure of distance, velocity is a measure of time.
