Review Forces and Motion Flashcard

Front

What is the 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

What does it mean if the net force is zero?

Back

If the net force is zero, the forces acting on an object are balanced, and the object will not accelerate.

Front

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

Back

Subtract the smaller force from the larger force and indicate the direction of the larger force.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = Net Force (F) / Mass (m) or a = F/m.

Front

If a force of 15 N is applied to a mass of 3 kg, what is the acceleration?

Back

5 m/s².

Front

What is speed?

Back

Speed is the rate at which an object changes its position, calculated as distance traveled over time.

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).

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
