Forces And Motion

Front 1

Force

Back 1

A force is a push or pull upon an object resulting from the object's interaction with another object.

Front 2

Vector

Back 2

A quantity having direction as well as magnitude, especially as determining the position of one point in space relative to another.

Front 3

Magnitude

Back 3

The great size or extent of something.

Front 4

Balanced Force

Back 4

Balance forces are two forces acting in opposite directions on an object, and equal in size.

Front 5

Unbalanced Force

Back 5

When two forces acting on an object are not equal in size, we say that they are unbalanced forces.

Front 6

Newtons

Back 6

One newton is the force required to cause a mass of one kilogram to accelerate at a rate of one meter per second squared in the absence of other force-producing effects.

Front 7

Mass

Back 7

The mass of an object is a measure of the number of atoms in it.

Front 8

Gravity

Back 8

Gravity is the force that attracts a body toward the center of the earth, or toward any other physical body having mass.

Front 9

Friction

Back 9

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.

Front 10

Inertia

Back 10

Inertia is the resistance of any physical object to any change in its state of motion.
