Question

Give two examples each of situations in which you push or pull to change the state of motion of objects.

Answer 1

Hint: Here, we will proceed by defining the term force. Then, we will be discussing whether force is a scalar quantity or a vector quantity. Then, we will be giving the main difference between push and pull along with two examples of each type.

Complete Step-by-Step solution:
Force is a push or pull on an object. Force may alter the shape of the object it's being applied to. Force may also alter the state of motion ( i.e., from rest to motion or from motion to rest) and direction of motion.
A Force is a vector quantity. A vector quantity is a quantity with a magnitude and a direction. To fully define the force acting on an object it is important to specify both the magnitude (size or numerical value) and the direction.
Push and pull types of forces act in different directions. The main difference between pull and push force is in the direction of the object that exerts force with respect to the applied force.
Two examples of push force are as follows:
Pushing a large box at rest to shift it from one room to another. It affects the box's state of motion. In this example, the box was at rest but as soon as a push force acts on the box, the box undergoes a displacement from its initial position and due to this displacement and does a certain amount of work. The force on the box, whose magnitude can be obtained by multiplying the force magnitude with the displacement magnitude.
A player using his foot to kick out a football. This shifts the ball's motion status from state of rest to state of motion.
Two examples of pull force are as follows:
Rope is forced into a well to draw water. This changes the motion status of the water bucket from state of rest to state of motion
Pulling a door to unlock it. This changes the drawer 's motion status from state of rest to state of motion.

Note- It is said that a quantity is scalar if it consists only of magnitude. Examples of push are often moving a door to open it and moving a chair to move it from one position to another position. To draw a glass of water towards oneself is also an example of pull type of force.
