Physics: Distance, Displacement, and Force

Imagine that you have a chance of going on a trip during your school ______.

What is the total length of the path of a motion called?

What is the linear length between the starting and ending positions of a motion called?

The displacement of a runner in the 400 meter race would be 400 meters.

What is the standard unit of measuring force?

What is the unit of measuring both 'distance' and 'displacement'?

Which of the following is NOT an example of applying force?

The speed of an object can be changed by applying a force.

The direction of an object's motion can be changed by applying a force.

Which of the following is the correct statement about force?

Distance and Displacement

Distance is the total length of the path traveled.
Displacement is the shortest distance between the starting and ending points of a motion. It has a direction.
The straight-line distance between two locations is always less than the total distance traveled along a path.
Distance is a scalar quantity (only magnitude), while displacement is a vector quantity (magnitude and direction).

Force

A force is a push or a pull.
Force has a magnitude and a direction.
The SI unit of force is the newton (N).
Forces can change the motion of an object (speed, direction, or both).

Activities

Activities are provided in the text to demonstrate how to measure distance, calculate displacement, and identify forces.
These activities include using maps, measuring with threads, applying forces and observing the effects.

Units of Measurement

The text discusses the international units for distance and force, which are metres (m) and newtons (N), respectively.
Other units for length like millimeters, centimeters, and kilometers, are also mentioned.

Motion

The text explains how forces can affect the speed of objects and change the direction of motion.
Applications of forces include moving objects that were initially at rest, changing the speed of objects, and changing their direction of motion.

This quiz covers key concepts in physics related to distance, displacement, and force. It highlights the differences between distance and displacement, as well as the definition and role of force in motion. Engage with activities designed to deepen your understanding of these fundamental topics.
