Question

Give two examples to show that a force is required to make a fast moving object to get slow​

Answer 1

Answer:

◾There are many examples of forces in our everyday lives:

◾weight force (i.e. the weight of something)

◾the force of a bat on the ball.

◾the force of the hair brush on hair when it is being brushed.

◾the force of your foot pushing on the pedal when you ride your bike.

Answer 2

Concept

A force is an influence that can change the motion of an object. A force can cause a material object to change its velocity, i.e. accelerate. Force can also be intuitively described as a push or pull. A force has both magnitude and direction, making it a vector quantity. Velocity is often used to mean speed, but force is related to acceleration. Newton's second law states that force equals mass times acceleration. F = ma The greater the force acting on the object, the greater will be its acceleration. The laws of physics dictate that the force of an impact increases with the square of the increasing speed.

Given

It is given that force is required to make a fast moving object to get slow

Find

We need to find two examples to show that a force is required to make a fast moving object to get slow

Solution

1) When a person in a car hits the brake, the car suddenly stops with a drop in speed

2) When the fielder catches the ball, the speed of the ball is reduced.

Hence the two examples are obtained to show that a force is required to make a fast moving object to get slow
