DB Mid-term Exam part 2

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in no change in motion of an object.

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined. If the net force is 0N, the object is either at rest or moving at a constant speed.

Front

What is the tilt of the Earth?

Back

The Earth is tilted at an angle of approximately 23.5 degrees.

Front

How does the tilt of the Earth affect seasons?

Back

The tilt of the Earth causes different parts of the Earth to receive varying amounts of sunlight throughout the year, leading to the changing seasons.

Front

What happens to an object at rest?

Back

If an object is not moving, the forces acting upon it are balanced.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

What does it mean if an object is moving at a constant speed?

Back

If an object is moving at a constant speed, it means that it is covering equal distances in equal intervals of time without speeding up or slowing down.

Front

What is inertia?

Back

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

Front

What is the significance of the Northern Hemisphere experiencing winter?

Back

When the Northern Hemisphere experiences winter, it is tilted away from the sun, resulting in shorter days and lower temperatures.

Front

What is the relationship between force and motion?

Back

Force is a push or pull that can cause an object to move, stop, or change direction. The motion of an object is directly affected by the forces acting on it.
