Physics Motion Quiz

What is the difference between speed and velocity?

• Speed is scalar, velocity is vector.

• Speed and velocity are the same thing.

• Speed is a vector quantity, velocity is a scalar quantity.

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

Define acceleration and provide an example.

• Acceleration is only applicable to objects in free fall.

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

• Acceleration is the same as velocity.

• 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 displacement in relation to motion.

• Displacement is the change in velocity of an object.

• Displacement is the speed of an object in motion.

• Displacement is the total distance traveled by an object regardless of direction.

• Displacement is the shortest distance between the initial and final positions of an object in a specific direction.

What is the formula to calculate average speed?

• Average Speed = Total Distance / Total Time

• Average Speed = Total Distance - Total Time

• Average Speed = Total Distance x Total Time

• Average Speed = Total Time / Total Distance

Describe the difference between distance and displacement.

• Distance and displacement are interchangeable terms in physics.

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

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

How does acceleration affect an object's motion?

• Acceleration has no effect on an object's motion

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

• Acceleration only affects the object's color

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

What is the equation for calculating final velocity?

• v = u + t

• v = u + a

• v = u * a * t

• v = u + at

Discuss the significance of the slope of a distance-time graph.

• The slope of a distance-time graph indicates the temperature of the object

• The significance of the slope of a distance-time graph is that it represents the speed of an object.

• The slope of a distance-time graph shows the color of the object

• The slope of a distance-time graph represents the weight of the object

Explain the concept of uniform motion.

• Uniform motion refers to an object moving in a straight line at an increasing speed.

• Uniform motion is when an object moves in a zigzag pattern at varying speeds.

• Uniform motion involves an object moving in a circular path at a constant speed.

• Uniform motion refers to an object moving in a straight line at a constant speed, covering equal distances in equal intervals of time.

How does acceleration due to gravity affect free fall motion?

• Acceleration due to gravity causes objects to decelerate during free fall.

• Acceleration due to gravity has no impact on free fall motion.

• Acceleration due to gravity causes objects to accelerate towards the Earth at a constant rate of 9.81 m/s^2, resulting in faster descent during free fall.

• Acceleration due to gravity causes objects to move sideways instead of downwards in free fall.
