Motion and Position

What is the difference between speed and velocity?

• Speed is scalar, velocity is vector.

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

• Speed is a vector, velocity is scalar.

• Speed and velocity are interchangeable terms.

Define acceleration and provide an example.

• Acceleration is the rate of change of position with respect to time. An example is a car moving at a constant speed of 60 mph.

• Acceleration is the rate of change of velocity with respect to time. An example is a car increasing its speed from 0 to 60 mph in 10 seconds.

• Acceleration is the rate of change of time with respect to velocity. An example is a car traveling at a constant speed of 60 mph.

• Acceleration is the rate of change of speed with respect to distance. An example is a car accelerating from 60 mph to 0 mph.

Explain the difference between distance and displacement.

• Distance is a scalar quantity, whereas displacement is a vector quantity.

• Distance and displacement have no relation to each other.

• Distance is a vector quantity, whereas displacement is a scalar quantity.

• Distance and displacement are the same thing.

How can you represent motion on a graph?

• By plotting the position of an object over time, where the x-axis represents time and the y-axis represents position.

• By labeling the x-axis with position and the y-axis with time

• By drawing a straight line on the graph

• By using a pie chart to show the speed of an object

What are vectors in motion and how are they used?

• Vectors in motion are used to analyze and predict the movement of objects by considering both the speed and direction of their motion.

• Vectors in motion are used to determine the chemical composition of substances.

• Vectors in motion are used to calculate the volume of irregular shapes.

• Vectors in motion are used to measure temperature changes in objects.

Describe the concept of projectile motion.

• Projectile motion does not involve any acceleration.

• Projectile motion involves circular motion.

• Projectile motion is only influenced by horizontal forces.

• Projectile motion involves the combination of horizontal motion at a constant velocity and vertical motion under the influence of gravity.

What is the formula to calculate speed?

• Speed = Distance / Time

• Speed = Distance + Time

• Speed = Time / Distance

• Speed = Distance x Time

How is velocity different from speed?

• Velocity is a scalar quantity, while speed is a vector quantity.

• Velocity is measured in kilometers per hour, while speed is measured in meters per second.

• Velocity is constant, while speed can change over time.

• Velocity includes direction, while speed does not.

What is the SI unit of acceleration?

• m/s

• km/h^2

• cm/s^2

• m/s^2

How can you calculate displacement from a velocity-time graph?

• Displacement is the slope of the velocity-time graph

• Displacement is the maximum velocity on the graph

• Displacement can be calculated by finding the area under the velocity-time curve.

• Displacement is the y-intercept of the velocity-time graph
