What is net force?

Back

Net force is the vector sum of all the forces acting on an object. It determines the object's acceleration.

Front

If two people are pushing a box with equal forces in opposite directions, what is the net force?

Back

The net force is 0 N, as the forces cancel each other out.

Front

What does a flat line on a distance-time graph indicate?

Back

A flat line indicates that the object is at rest, with no change in position over time.

Front

What does a line going up on a distance-time graph indicate?

Back

A line going up indicates that the object is moving away from the starting point, showing positive velocity.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

How do you calculate net force when multiple forces are acting in the same direction?

Back

To calculate net force, sum all the forces acting in the same direction.

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.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object over time.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) can be calculated using the formula a = (final velocity - initial velocity) / time.
