What is a scalar quantity?

Back

A scalar quantity is a physical quantity that has only magnitude and no direction. Examples include mass, temperature, and speed.

Front

What is a vector quantity?

Back

A vector quantity is a physical quantity that has both magnitude and direction. Examples include displacement, velocity, and force.

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, along with the direction. It is a vector quantity.

Front

What is distance?

Back

Distance is the total length of the path traveled by an object, regardless of direction. It is a scalar quantity.

Front

What are the units for velocity?

Back

The units for velocity are meters per second (m/s).

Front

What is the unit for force?

Back

The unit for force is Newton (N).

Front

What are the units for time?

Back

The units for time are seconds (s).

Front

What is the formula for calculating velocity?

Back

Velocity (v) is calculated using the formula: v = \frac{d}{t}, where d is displacement and t is time.

Front

What is the formula for calculating density?

Back

Density (ρ) is calculated using the formula: ρ = \frac{m}{V}, where m is mass and V is volume.

Front

What is the relationship between mass and weight?

Back

Weight (W) is the force exerted by gravity on an object and is calculated using the formula: W = mg, where m is mass and g is the acceleration due to gravity.
