About this worksheet

This helpful Class 9 Science revision worksheet focuses on the fundamental concepts of motion, specifically providing numerical practice for distance, speed, and velocity. Understanding how objects move is a cornerstone of physics and is crucial for building a strong foundation in science. This worksheet is designed to help students solidify their grasp of uniform and non-uniform motion through engaging problems. Perfectly aligned with the CBSE and NCERT Class 9 Science curriculum, it is ideal for students who have already covered the basic theory and are looking to enhance their problem-solving skills. Teachers can use this as a valuable in-class activity, while parents will find it perfect for reinforcing learning at home, ensuring their child is well-prepared for assessments.

What your child will learn

• Practice calculating distance, speed, and velocity for various scenarios.
• Identify the differences between uniform and non-uniform motion.
• Apply relevant formulas to solve numerical problems related to motion.
• Formulate clear explanations for concepts of instantaneous and average speed/velocity.
• Solve multi-step problems involving changes in motion.

Understanding the concept

Motion describes how an object changes its position over time. When we talk about motion, two key terms are distance and displacement. Distance is the total path length covered by an object, regardless of direction. For example, if you walk 5 meters north and then 3 meters south, your total distance covered is 8 meters. Displacement, on the other hand, is the shortest distance from the initial to the final position, including direction. In our example, your displacement would be 2 meters north. This distinction is vital. Speed is defined as the rate at which an object covers distance (distance divided by time), while velocity is the rate at which an object changes its displacement (displacement divided by time), meaning it includes both magnitude and direction. For instance, a car traveling at 60 km/h has a certain speed. If we say it's traveling at 60 km/h towards the east, we are talking about its velocity. Motion can be uniform, where an object covers equal distances in equal intervals of time, or non-uniform, where it covers unequal distances in equal intervals of time. An object moving in a straight line at a constant speed is an example of uniform motion, whereas a car accelerating or decelerating exhibits non-uniform motion. Understanding these concepts allows us to describe and predict the movement of everyday objects around us.

Tips for parents & teachers

• Encourage your child to draw diagrams for each problem to visualise the motion.
• Remind them to always include units with their answers (e.g., m/s, km/h).
• Have them explain their reasoning for choosing specific formulas for each problem.
• Review the basic definitions of distance, displacement, speed, and velocity before starting.
• Work through one or two problems together to model effective problem-solving strategies.
