Forces Test Review

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, which varies depending on the gravitational pull of the planet.

Front

What is net force?

Back

Net force is the total force acting on an object after all the individual forces are combined. It determines the object's motion.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object and occurs between surfaces in contact, in solids, liquids, and gases.

Front

How does gravity affect weight?

Back

Gravity affects weight by determining how much force is exerted on an object due to its mass and the gravitational pull of the planet.

Front

What happens when two objects push against each other?

Back

When two objects push against each other, they exert equal and opposite forces, which can cause them to move apart or remain stationary.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is the formula for calculating weight?

Back

Weight (W) = mass (m) × gravitational acceleration (g).

Front

What is the effect of balanced forces on an object?

Back

Balanced forces do not change the motion of an object; it remains at rest or continues to move at a constant speed.

Front

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause an object to accelerate, changing its speed or direction.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two masses, which depends on their masses and the distance between them.
