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 motion and is measured in Newtons (N).

Front

How do you find the net force when two forces are acting in the same direction?

Back

You add the magnitudes of the two forces together.

Front

What is a reference point?

Back

A reference point is a stationary object used to determine the position or motion of another object.

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, along with the direction.

Front

When is an object considered to be in motion?

Back

An object is in motion when it changes position relative to a reference point.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the straight line distance from the starting point to the ending point.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What does it mean if the net force on an object is zero?

Back

If the net force is zero, the object is either at rest or moving at a constant velocity.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, measured in meters per second squared (m/s²).

Front

What is the formula for calculating net force?

Back

Net force (F_net) = mass (m) × acceleration (a).
