Net Force Review

Front

What is the formula to calculate force?

Back

F = MA (Force = Mass x Acceleration)

Front

What is the unit of force?

Back

Newton (N)

Front

What does acceleration measure?

Back

Acceleration measures how quickly an object's velocity changes.

Front

What is net force?

Back

Net force is the total force acting on an object after all the forces are combined.

Front

If two forces are acting in the same direction, how do you find the net force?

Back

Add the magnitudes of the two forces together.

Front

What happens when two forces of equal magnitude act in opposite directions?

Back

The net force is zero, and the object remains at rest or in constant motion.

Front

What is the acceleration of a 0.20 kg coconut falling under gravity?

Back

1.96 N (Force due to gravity = Mass x Acceleration due to gravity = 0.20 kg x 9.80 m/s²)

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass (Weight = Mass x Gravity).

Front

What does it mean if an object is in equilibrium?

Back

The net force acting on the object is zero, meaning all forces are balanced.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).
