Forces Remediation

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two objects with mass. It pulls objects toward each other, such as the Earth pulling objects toward its center.

Front

What is air resistance?

Back

Air resistance is a force that opposes the motion of objects moving through the air, acting in the opposite direction to the object's velocity.

Front

How do you calculate weight?

Back

Weight is calculated using the formula: Weight (W) = mass (m) × acceleration due to gravity (g).

Front

What is the normal force?

Back

The normal force is the support force exerted by a surface perpendicular to the object resting on it, balancing the weight of the object.

Front

What does 'little g' represent?

Back

'Little g' represents the acceleration due to gravity at the surface of the Earth, approximately 9.8 m/s².

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, while mass is the amount of matter in the object. Weight depends on mass and the gravitational field strength.

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula: F = mass (m) × acceleration (a).

Front

What is static friction?

Back

Static friction is the force that keeps an object at rest and prevents it from starting to move when a force is applied.

Front

What is kinetic friction?

Back

Kinetic friction is the force that opposes the motion of two surfaces sliding past each other.

Front

What is the difference between mass and weight?

Back

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