Flashcard Forces

Front

What is net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. It determines the object's acceleration.

Front

What happens to an object's velocity when forces act on it?

Back

An object's velocity can change by altering its speed, direction, or both.

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.

Front

If an object has twice the mass, what happens to its weight?

Back

The weight of the object will also be twice as much, since weight is directly proportional to mass.

Front

What is the force required to keep a cannonball moving in space?

Back

Zero, since no force is required to keep it moving in frictionless space.

Front

What is the difference between mass and weight?

Back

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

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the formula for calculating weight?

Back

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

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and opposite, causing a change in the object's motion.
