Question

d) Write down three ways of minimising friction.
is the difference between mass and weight?​

Answer 1

Answer:

Methods for decreasing friction:

Make the surfaces smoother. Rough surfaces produce more friction and smooth surfaces reduce friction.

Lubrication is another way to make a surface smoother. ...

Make the object more streamlined. ...

Reduce the forces acting on the surfaces. ...

Reduce the contact between the surfaces.

The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s2.
