Answer 1

Answer:

Step-by-step explanation:Answer:

4.)1) displacement = 0 2) 40km/h

5.) uniform circular motion means that the object is moving at a fix point or in a circular path with no change in motion speed. For example it can be a watch , moon rotation around earth , earth rotation around sun , etc

uniform circular motion is also known as accelerated motion because it's direction of motion is always changing

7.) Newton first law of motion is that every object will remain in rest or in uniform motion untill it is compelled to change it position by any external force.

we jamp of water from clothes before spreading them on string because the water is in rest on clothes, so when we jamp of the water it comes in the motion and falls down, become easy for remaining water to evaporate and clothes dry early.

1.) displacement is said to be positive when a object or vehicle move forward from it's initial point and it is said to be negative when it move reverse, displacement is said to be zero when we move a object in a circular path or a path in which we return to our initial point

2.)

1.)

2.) car has been accelerating o.5m/s

3.) we can say a body is in uniform acceleration when body is moving with an constant speed

3.) example of inertia in our daily life

1) throwing the ball up in the sky

2) rolling the ball

3) kite changes in motion due to wind
