1st Semester Final Physical Science

Front

What happens to the motion of an object when an unbalanced force acts on it?

Back

The motion of the object changes.

Front

How many liters are in 1200 milliliters?

Back

1.2 liters.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is the weight of an object on Earth if it has a mass of 42 kg?

Back

Weight = mass × gravity = 42 kg × 9.81 m/s² = 411.6 N.

Front

What is momentum and how is it calculated?

Back

Momentum = mass × velocity.

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.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as Weight = mass × gravity.

Front

How do you convert milliliters to liters?

Back

To convert milliliters to liters, divide the number of milliliters by 1000.

Front

What is the acceleration of a car that comes to a stop from 14 m/s in 3.2 seconds?
