Front

What is static electricity?

Back

Static electricity is the accumulation of electric charge on the surface of objects, often caused by friction. An example is lightning.

Front

What types of charges attract each other?

Back

Positive and Negative charges attract each other.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What two factors affect the force of gravity between two objects?

Back

The mass of the objects and the distance between them affect the force of gravity.

Front

What type of charge does a substance have if it has more electrons than protons?

Back

A negative charge.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma).

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated as KE = 1/2 mv².

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, such as gravitational potential energy.
