2024 Forces & Friction Flashcard Review

Front

What is net force?

Back

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

Front

What happens when the net force is zero?

Back

When the net force is zero, the forces acting on an object are balanced, resulting in no movement or constant velocity.

Front

What are unbalanced forces?

Back

Unbalanced forces occur when the net force acting on an object is not zero, causing the object to accelerate in the direction of the net force.

Front

Define friction.

Back

Friction is a force that opposes the motion of two surfaces in contact, acting parallel to the surfaces.

Front

What are balanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

How does friction affect motion?

Back

Friction slows down or stops the motion of an object, depending on the surfaces in contact and the force applied.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

Give an example of unbalanced forces in real life.

Back

A car accelerating when the driver presses the gas pedal is an example of unbalanced forces.

Front

What is the effect of increasing net force on an object?

Back

Increasing the net force on an object will increase its acceleration, according to Newton's second law of motion.

Front

What is static friction?

Back

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