ADV 12/4 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

How do you calculate net force when forces are acting in opposite directions?

Back

To calculate net force, subtract the smaller force from the larger force and indicate the direction of the larger force.

Front

What is the unit of force?

Back

The unit of force is Newton (N).

Front

What does it mean for an object to be in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero, resulting in no acceleration.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces result in no change in motion, while unbalanced forces cause an object to accelerate.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be caused by a change in speed or direction.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = (Final Velocity - Initial Velocity) / Time.

Front

What does a constant speed graph look like?

Back

A constant speed graph is a straight line, indicating that the object is moving at a steady rate.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting parallel to the surface of contact.

Front

What is the role of gravity in motion?

Back

Gravity is a force that pulls objects toward each other, affecting their motion and acceleration.
