What is the formula to calculate density?

• Density = Mass * Volume.

• Density = Volume / Mass.

• Density = Mass / Volume

• Density = Weight / Volume.

What is the formula to calculate speed?

• Speed = Distance x Time

• Speed = Distance + Time

• Speed = Distance - Time

• Speed = Distance / Time

What is the formula to calculate acceleration?

• Acceleration = (final velocity - initial velocity) * time.

• Acceleration = (final velocity * initial velocity) / time.

• Acceleration = (final velocity - initial velocity) / time

• Acceleration = (final velocity + initial velocity) / time.

What is the formula to calculate force?

• force = mass x acceleration

• force = mass + acceleration

• force = mass - acceleration

• force = mass / acceleration

What is the formula to calculate work?

• work = force - distance

• work = force / distance

• work = force + distance

• work = force x distance

What is the formula to calculate power?

• P = W/t

• P = mgh

• P = F/d

• P = V/I
