Answer 1

MARK ME AS THE BRAINLIEST

Answer:

In physics, a force is any interaction that, when unopposed, will change the motion of an object.

1) A force can move a stationary object

Ex-The force of engine makes a stationery car to move.

2) A force can stop a moving object.

Ex-The force of brakes can stop a moving car.

3) A force can change the speed of a moving object.

Ex-When a hockey player hits a moving ball, the speed of ball increases.

4) A force can change the direction of a moving object.

Ex-In a cricket match, when a moving cricket ball is hit by a bat ,then the direction cricket ball changes.

Answer 2

$\huge{\fbox{\fbox{\bigstar{\mathfrak{\red{Answer}}}}}}$

In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.

FOUR EFFECTS ARE :--.

1. A force can move a stationary object. Ex-The force of engine makes a stationery car to move.
2. A force can stop a moving object. Ex-The force of brakes can stop a moving car.
3. A force can change the speed of a moving object. ...
4. A force can change the direction of a moving object.
