Here are two graphs that represent the motion of two different objects. Copy the speed-time graph. Use your graph to explain how you would find the object's acceleration.

The slope in the velocity-time graph represents the acceleration. The slope is defined as the ratio of change in y-axis to change in the x-axis. As shown in the figure, the velocity of the particle will increase linearly with respect to time. The slope of the graph will give the magnitude of acceleration. Example: If the acceleration of a particle is constant (k) and is positive, the initial velocity is zero, and then the velocity increases linearly. The slope of the velocity-time graph will give the acceleration.

The table shows the difference between vector and scalar quantities. Quantity Description Examples has magnitude only has magnitude and direction Copy the table and complete the first column with the word vector and scalar in the correct rows.

A scalar quantity is defined as the physical quantity that has only magnitude, for example, mass and electric charge. On the other hand, a vector quantity is defined as the physical quantity that has both magnitude as well as direction like force and weight. Quantity Description Examples Scalar Has magnitude only Mass, Electric charge Vector Has magnitude and direction Force, Weight For example, distance is a scalar quantity and displacement is a vector quantity.

A runner travels 400 m in 50 s . What is her average speed?

Distance travelled, s = 400 m Time, t = 50 s Average speed can be calculated by dividing the total distance travelled by the total time. Average speed = Total distance Total time is the required formula. So, average speed, V a v = 400 50 = 8 m / s
