Understanding Motion for Grade 6

What is the difference between speed and velocity?

• Velocity measures distance only, not direction.

• Speed is scalar; velocity is vector (includes direction).

• Speed is always greater than velocity.

• Speed can be negative, while velocity cannot.

If a car travels 60 km in 1 hour, what is its speed?

• 70 km/h

• 120 km/h

• 60 km/h

• 50 km/h

Define uniform motion with an example.

• An example of uniform motion is a car traveling at a constant speed of 60 km/h on a straight road.

• A person walking in a zigzag pattern across a park.

• A train accelerating from a stop to a high speed.

• A bicycle moving at varying speeds on a hilly terrain.

What type of motion is exhibited by a pendulum?

• Linear motion

• Rotational motion

• Random motion

• Periodic motion

If a cyclist travels 30 km in 2 hours, what is the distance covered?

• 25 km

• 40 km

• 35 km

• 30 km

What is the formula to calculate speed?

• Speed = Time / Distance

• Speed = Distance / Time

• Speed = Distance - Time

• Speed = Distance + Time

Identify the type of motion when an object moves in a straight line.

• Periodic motion

• Linear motion

• Rotational motion

• Random motion

If a train travels at a speed of 80 km/h, how far will it go in 3 hours?

• 180 km

• 300 km

• 120 km

• 240 km

What is the term for the rate of change of distance?

• Momentum

• Speed

• Velocity

• Acceleration

Explain what is meant by circular motion.

• Circular motion is the movement of an object along a circular path, influenced by a centripetal force.

• Circular motion is the oscillation of an object back and forth in a circular pattern.

• Circular motion refers to the linear movement of an object in a straight line.

• Circular motion is the rotation of an object around its own axis without any external force.
