Physics Motion Basics

What is the difference between distance and displacement?

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

• Distance and displacement are interchangeable terms.

• Distance and displacement have the same magnitude.

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

How is speed different from velocity?

• Speed is the magnitude of velocity.

• Speed and velocity are the same thing.

• Speed is always negative while velocity can be positive or negative.

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

Define acceleration and provide an example.

• Acceleration is only applicable to objects moving in a straight line.

• Acceleration is the same as velocity.

• Acceleration is the rate of change of speed with respect to distance.

• Acceleration is the rate of change of velocity with respect to time. For example, when a car accelerates from 0 to 60 mph in 6 seconds, the acceleration is approximately 10 mph/s.

Explain the concept of graphing motion.

• Graphing motion involves plotting the weight of an object against time on a graph.

• Graphing motion is the process of representing the position of an object over time on a graph, where the x-axis represents time and the y-axis represents position.

• Graphing motion is the act of displaying the color of an object as it moves over time.

• Graphing motion is the process of representing the speed of an object over time on a graph.

What are the equations of motion?

• v = u + t, s = ut + (1/2)at^2, v^2 = u^2 + 2as

• v = u + at, s = ut + (1/2)at, v^2 = u^2 + 2as

• v = u + at, s = ut + (1/2)at^2, v^2 = u^2 + 2as

• v = u + at, s = ut + (1/2)at^2, v^2 = u^2 + as

How can you calculate distance traveled from a velocity-time graph?

• Find the maximum velocity on the graph.

• Calculate the area under the velocity-time graph curve.

• Calculate the slope of the velocity-time graph.

• Divide the final velocity by the initial velocity.

What does a flat line on a distance-time graph indicate?

• The object is moving at a constant speed

• The object is decelerating

• The object is accelerating

• The object is stationary.

How does acceleration affect an object's motion?

• Acceleration changes an object's velocity over time, resulting in changes to its speed, direction, or both.

• Acceleration always causes an object to slow down

• Acceleration has no impact on an object's motion

• Acceleration only affects an object's speed, not its direction

Describe the relationship between speed and time in uniform motion.

• Speed and time have an exponential relationship in uniform motion.

• Speed and time have an inverse relationship in uniform motion.

• Speed and time have no relationship in uniform motion.

• Speed and time have a linear relationship in uniform motion.

What is the significance of the slope of a velocity-time graph?

• The slope of a velocity-time graph indicates the distance traveled by an object.

• The slope of a velocity-time graph represents the acceleration of an object.

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

• The slope of a velocity-time graph shows the time taken for an object to change direction.
