Activity 4: Look for the meaning of the following words 1. Law of inertia 2. Law of acceleration 4. Inertia 5. Acceleration 7. Unit for acceleration 3. Law of Interaction 6.Unit for mass 8. Unit for force
An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.
2.Law of Acceleration
A force upon an object causes it to accelerate according to the formula net force equals mass x acceleration. The acceleration of the object is directly proportional to the force and inversely proportional to the mass.
3.Law of Interaction
In every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object.
4.Inertia
The inherent property of a body that makes it oppose any force that would cause a change in its motion. A body at rest and a body in motion both oppose forces that might cause acceleration.
5.Acceleration
Rate at which velocity changes with time, in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down.
6.Unit for Mass
Unit for Mass is a dimensionless quantity representing the amount of matter in a particle or object. The standard unit of mass in the International System is the kilogram.
7.Unit for Acceleration
Unit of acceleration is the metre per second per second. Definition. The snewton is that force which, when acting on a mass of one kilogram, produces an acceleration of one metre per second per second.
8.Unit for Force
The SI unit of force is the newton, symbol N.The base units relevant to force are The metre, unit of length, symbol m. The kilogram, unit of mass, symbol kg.
