Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined. It determines the object's acceleration and direction.

Front

If an object is pulled up with a force of 10 N and down with a force of 15 N, what is the net force?

Back

5 N down.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What does it mean when we say an object has momentum?

Back

Momentum is the product of an object's mass and its velocity. It is a vector quantity, meaning it has both magnitude and direction.

Front

If a force acts on an object, what will happen to its momentum?

Back

The momentum will definitely change.

Front

What is the formula to calculate weight?

Back

Weight (W) = mass (m) × gravitational acceleration (g).

Front

What is the mass of a 60 N object?

Back

6 kg.

Front

What is a vector?

Back

A vector is a quantity that has both magnitude and direction, such as force, velocity, and acceleration.

Front

Which of the following must be included with magnitude to represent a vector?

Back

Direction.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses. It is proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
