Understanding Motion Concepts

What is the formula for calculating speed?

• Speed = Distance + Time

• Speed = Distance - Time

• Speed = Time / Distance

• Speed = Distance / Time

Define velocity and how it differs from speed.

• Velocity is the same as speed.

• Velocity is a vector quantity that includes direction; speed is a scalar quantity that does not.

• Speed includes direction while velocity does not.

• Velocity is a scalar quantity that measures distance.

What is the difference between distance and displacement?

• Distance and displacement are the same concept.

• Distance is the total path length traveled; displacement is the shortest straight-line distance between two points.

• Displacement measures the total time taken for a journey.

• Distance is always greater than displacement.

How is acceleration defined in physics?

• Acceleration is the total distance traveled over time.

• Acceleration is the force applied to an object.

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

• Acceleration is the speed of an object at a given moment.

If a car travels 100 km in 2 hours, what is its speed?

• 25 km/h

• 100 km/h

• 75 km/h

• 50 km/h

A person walks 3 km east and then 4 km north. What is their displacement?

• 5 km

• 7 km

• 4 km

• 3 km

What is the unit of acceleration in the International System of Units (SI)?

• ft/s

• km/h

• m/s

• m/s²

If an object is moving at a constant speed, what is its acceleration?

• 5 m/s²

• -3 m/s²

• 0

• 2 m/s²

How do you calculate the average velocity of an object?

• Average velocity = Total Time / Total Displacement

• Average velocity = Initial Velocity + Final Velocity

• Average velocity = Total Displacement / Total Time

• Average velocity = Total Distance / Total Time

What does a negative acceleration indicate about an object's motion?

• An object is at rest.

• An object is moving in a straight line.

• An object is slowing down.

• An object is speeding up.
