Speed and Acceleration Problems

If a car travels at a steady speed of 60 km/h for 2 hours, how far does it travel?

• 100 km

• 110 km

• 120 km

• 130 km

What is a possible unit for acceleration?

• meters per second squared (m/s²)

• kilometers per hour (km/h)

• grams per cubic centimeter (g/cm³)

• joules per second (J/s)

What does a speed-time graph represent?

• It shows the distance traveled over time.

• It shows how speed changes over time, where the slope represents acceleration.

• It represents the total energy of an object over time.

• It indicates the direction of motion of an object.

How do you calculate distance traveled if you know speed and time?

• Distance = Speed + Time.

• Distance = Speed - Time.

• Distance = Speed x Time.

• Distance = Speed / Time.

What is the formula for calculating acceleration?

• Acceleration = (Final Velocity + Initial Velocity) / Time

• Acceleration = (Final Velocity - Initial Velocity) * Time

• Acceleration = (Final Velocity - Initial Velocity) / Time

• Acceleration = Final Velocity / Time

What is speed?

• Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

• Speed is the total distance covered in a journey regardless of time.

• Speed is the rate at which an object accelerates over time.

• Speed is the maximum distance an object can travel in a given time.

What is the difference between speed and velocity?

• Speed is a vector quantity (magnitude and direction), while velocity is a scalar quantity (magnitude only).

• Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

• Speed and velocity are the same; both are scalar quantities.

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

If a polar bear swims at an average speed of 2.6 m/s for 120 seconds, how far does it travel?

• 250 m

• 300 m

• 312 m

• 350 m

What does it mean if an object is stationary?

• An object is moving at a constant speed.

• An object is not moving and its position does not change over time.

• An object is accelerating in a straight line.

• An object is in motion relative to another object.

What is a unit of distance?

• meters (m)

• liters (L)

• grams (g)

• seconds (s)
