MOTION

What is motion?

• Change in an object's weight over time.
• Change in an object's size over time.
• Change in an object's position over time.
• Change in an object's color over time.

Which type of motion describes a car driving down a straight road?

• Rotational motion
• Random motion
• Linear motion
• Periodic motion

A swinging pendulum is a good example of which type of motion?

• Motion that goes in a straight line.
• Motion that repeats itself at regular times.
• Motion that moves without a pattern.
• Motion that spins around a point.

A runner travels 200 meters in 25 seconds. What is their speed?

• 8 meters per second
• 225 meters per second
• 175 meters per second
• 5000 meters per second

What is the main difference between speed and velocity?

• Speed includes direction, velocity does not.
• Velocity includes direction, speed does not.
• Speed is measured in km/h, velocity in m/s.
• Velocity is always faster than speed.

A student claims that a car cruising steadily on a highway at 80 km/h has no acceleration. Is this claim accurate?

• Yes, because its speed is constant.
• No, because it is still moving forward.
• Yes, if it's going in a straight line.
• No, because velocity includes direction.

If you walk 50 meters to a store and then walk 50 meters back home, what is your total displacement?

• 100 meters
• 50 meters
• 0 meters
• 25 meters

A person runs 100 meters East, then 100 meters West, ending exactly where they started. How do their distance and displacement compare?

• Both distance and displacement are 200 meters.
• Both distance and displacement are zero.
• Distance is 200 meters, displacement is zero.
• Distance is zero, displacement is 200 meters.

A basketball is thrown straight up, pauses at its highest point, then falls down. What can be inferred about its velocity at the highest point?

• Its velocity is momentarily zero.
• Its velocity changes direction upwards.
• Its velocity is constant.
• Its velocity is at its maximum.

Why is understanding motion useful in everyday life?

• It helps us understand ancient languages.
• It teaches us about different types of plants.
• It explains why historical events happened.
• It helps predict how objects will move.
