Motion Assessment

A car moves in a straight line for 10 seconds at a constant speed, then stops for 5 seconds, and finally moves back to its starting point in 10 seconds. Which type of motion best describes the car's movement during the first 10 seconds?

• Oscillatory motion

• Uniform motion

• Non-uniform motion

• Rotational motion

A ball is thrown vertically upward. Which of the following graphs best represents the velocity of the ball as a function of time until it returns to the thrower's hand?

• A straight horizontal line

• A straight line with a negative slope passing through the origin

• A curve that increases and then decreases

• A straight line with a positive slope

A cyclist travels 60 km in 3 hours. What is the average speed of the cyclist?

• 15 km/h

• 20 km/h

• 18 km/h

• 25 km/h

A car's velocity changes from 10 m/s to 30 m/s in 5 seconds. What is the acceleration of the car?

• 2 m/s²

• 4 m/s²

• 5 m/s²

• 6 m/s²

Which of the following scenarios is an example of non-uniform motion?

• A train moving at a constant speed on a straight track

• A runner increasing speed during a race

• A clock’s second hand moving around the dial

• A car parked in a garage

The distance-time graph of an object is a straight line sloping upwards. What does this indicate about the object's motion?

• The object is at rest

• The object is moving with constant speed

• The object is accelerating

• The object is decelerating

A car travels 100 meters north in 20 seconds, then 100 meters south in 20 seconds. What is the car’s average velocity for the entire trip?

• 0 m/s

• 2.5 m/s north

• 5 m/s south

• 10 m/s north

A bus slows down from 25 m/s to 5 m/s in 4 seconds. What is its deceleration?

• 5 m/s²

• 4 m/s²

• 6.25 m/s²

• 10 m/s²

Which of the following best describes rotational motion?

• A car moving in a straight line

• A fan blade spinning around its axis

• A ball bouncing up and down

• A person walking in a park

Which graph would represent an object that is accelerating?

• A straight, horizontal line on a velocity-time graph

• A straight, sloped line on a distance-time graph

• A curved line on a velocity-time graph

• A straight, vertical line on a distance-time graph
