Basic Physics

It is something that causes stationary objects to move, change speed or direction of motion of moving bodies. It can also change the size or shape of an object.

• Acceleration

• Magnetism

• Force

• Gravity

NGSS.MS-PS2-2

The _____________ states that if a body is at rest, it will continue to remain at rest or will keep moving if it is moving unless acted upon by a force.

A quantity which has both magnitude and direction.

• Scalar quantity

• Vector Quantity

• Speed

• Velocity

It is the force between two surfaces in contact. It has a direction opposite to the motion and parallel to the surface.

• Tension

• Magnetic Field

• Friction

• Non-contact Force

What is the unit of electrical resistance?

• Volt

• Ampere

• Ohm

• Watt

It is the gravitational force exerted by the Earth on any object. It is measured in newton (N) because it is a kind of force.

• Weight

• Mass

• Gravity

• Contact force

NGSS.MS-PS2-4

It is a branch of physics dealing with the behaviour of bodies that are at rest, or moving at a constant velocity under the influence of two or more forces.

• Combining Forces

• Net

• Net Force

• Statics

NGSS.HS-PS2-1

A quantity which has only magnitude and is completely specified by a number and a unit.

• Vector

• Resultant Force

• Scalar Quantity

• Net Force

The point where the whole weight of a certain body can be considered concentrated.

• Point of Equilibrium

• Static Equilibrium

• Center of Gravity

• Net

A change in position of any body or object with respect to a fixed reference point.

• Motion

• Uniform Motion

• Circular Motion

• Linear Motion
