Answer 1

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.

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.

The SI unit of force is the newton, symbol N. ... The metre, unit of length — symbol m. The kilogram, unit of mass — symbol kg. The second, unit of time — symbol s.

Answer 2
