Movement and Position

What is the SI unit for speed?

• m/s

• miles/h

• km/h

• kg

Define displacement in terms of movement and position.

• Displacement is the change in position of an object.

• Displacement is the force acting on an object.

• Displacement is the distance traveled by an object.

• Displacement is the speed of an object.

Explain the difference between distance and displacement.

• Distance is the total length of the path traveled, while displacement is the shortest distance between the initial and final positions in a specific direction.

• Distance and displacement are interchangeable terms in physics.

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

• Distance is the shortest path traveled, while displacement is the total length of the path in any direction.

How can you calculate average speed?

• Average Speed = Total Distance x Total Time

• Average Speed = Total Time / Total Distance

• Average Speed = Total Distance / Total Time

• Average Speed = Total Distance - Total Time

What is the formula for calculating velocity?

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

• velocity = distance / time

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

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

Describe the motion of an object with constant speed.

• The object covers different distances in equal intervals of time

• The object moves faster and faster over time

• The object changes direction constantly

• The motion of an object with constant speed is characterized by covering equal distances in equal intervals of time.

What is the difference between speed and velocity?

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

• Speed is scalar, velocity is vector.

• Speed is a vector, velocity is scalar.

• Speed and velocity are the same thing.

How does acceleration affect an object's motion?

• Acceleration always causes an object to move in a straight line

• Acceleration has no impact on an object's motion

• Acceleration only affects the color of an object

• Acceleration changes an object's velocity by speeding it up, slowing it down, or changing its direction.

Explain the concept of distance-time graphs.

• distance - time graph show the speed of an object over time based on their position.

• distance-time graphs show the relationship between speed and distance traveled

• Different shapes on the graph convey information about the object's acceleration

• distance-time graphs have the vertical axis representing time and the horizontal axis representing position

What is the relationship between distance-time graphs and speed?

• Speed is determined by the color of the distance-time graph

• Distance-time graphs have no relation to speed

• Distance-time graphs provide information about the speed of an object based on the slope of the graph.

• The shape of the distance-time graph indicates the speed of an object
