Front

What is the difference between scalars and vectors?

Back

Scalars are quantities that have only magnitude, while vectors have both magnitude and direction.

Front

What is a Free Body Diagram (FBD)?

Back

A Free Body Diagram (FBD) is a graphical representation used to visualize the forces acting on an object.

Front

What is an example of a non-contact force?

Back

Electromagnetic force is an example of a non-contact force.

Front

What is the SI unit for measuring distance?

Back

The SI unit for measuring distance is the meter (m).

Front

How do you calculate the height of a drop using gravitational acceleration?

Back

Use the formula h = 0.5 * g * t^2, where g is the acceleration due to gravity (9.81 m/s²) and t is the time in seconds.

Front

What is gravitational acceleration?

Back

Gravitational acceleration is the acceleration of an object due to the force of gravity, approximately 9.81 m/s² on Earth.

Front

What are the four fundamental forces in nature?

Back

The four fundamental forces are gravitational force, electromagnetic force, weak nuclear force, and strong nuclear force.

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = m * a, where m is mass and a is acceleration.

Front

What is inertia?

Back

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

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.
