New cards

Force

A push or pull that can cause an object to stop, move, speed up, slow down, or change direction.

2
New cards

what is a resultant force?

The net force obtained by adding forces in the same direction and subtracting forces in the opposite direction.

3
New cards

state newton's 1st Law

An object remains at rest or in uniform motion unless acted upon by a resultant force.

4
New cards

state newton's 2nd Law

The acceleration of an object is directly proportional to the resultant force acting on it.

5
New cards

what is centripetal Force

The force that acts towards the center of an object in circular motion to cause acceleration.

6
New cards

what is centre of Gravity

The point where the entire weight of a body appears to act.

7
New cards

what is friction

A force that opposes an object's motion, causing it to slow down.

8
New cards

what do you understand by the term extension

The change in length of a body, calculated as final length minus initial length.

9
New cards

state hooke's Law

The force applied on a body is directly proportional to its extension within the limit of proportionality.

10
New cards

what is spring Constant

The force per unit extension of a spring, denoted as k.

11
New cards

what is moments

The turning effect of a force about a point, calculated as force multiplied by perpendicular distance from the pivot.

12
New cards

describe pressure

The force acting per unit area, calculated as force divided by area.

13
New cards

describe liquid Pressure

The pressure exerted by a liquid on an object immersed in it, depending on depth and density of the liquid.

14
New cards

what is work Done

Work is done when an object moves in the direction of the applied force, calculated as force multiplied by distance.

15
New cards

describe power

The rate of transfer of energy, calculated as energy transferred divided by time.

16
New cards

describe energy

The capacity of something to do work, with various forms like kinetic, gravitational potential, elastic, chemical, nuclear, and internal energy.
