Honors Science Exam 1st Sem. 24 25

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It means that an object at rest stays at rest, and an object in motion continues in motion unless acted upon by an external force.

Front

What is the formula for calculating resultant force?

Back

Resultant force can be calculated by adding all the forces acting on an object, taking into account their direction. If forces are in opposite directions, subtract the smaller force from the larger one.

Front

What two variables affect the gravitational force between objects?

Back

The gravitational force between two objects is affected by their mass and the distance between them. Greater mass results in a stronger gravitational pull, while greater distance weakens the pull.

Front

What is a digital wave?

Back

A digital wave is a type of signal that represents data as discrete values, typically in binary form (0s and 1s). It contrasts with an analog wave, which represents data in a continuous form.

Front

How do electromagnets work?

Back

Electromagnets work by generating a magnetic field when an electric current flows through a coil of wire. The strength of the magnetic field can be controlled by adjusting the current.

Front

What happens when you turn off the electric current in an electromagnet?

Back

When the electric current is turned off, the magnetic field disappears, allowing any attached metal objects to be released.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, and it is calculated by multiplying the mass of the object by the acceleration due to gravity (Weight = Mass x Gravity).

Front

What is friction?

Back

Friction is the force that opposes the motion of an object when it is in contact with another surface. It can cause objects to slow down or stop.

Front

What is the difference between mass and volume?

Back

Mass is the amount of matter in an object, while volume is the amount of space that an object occupies. Mass is measured in kilograms, and volume is measured in liters or cubic meters.

Front

What is gravity?

Back

Gravity is a force that attracts two bodies toward each other. It is what keeps us grounded on Earth and causes objects to fall when dropped.
