Front

What is weight?

Back

Weight is a measurement of the force of gravity acting on an object with mass.

Front

What is the SI unit for force?

Back

The SI unit for force is the Newton.

Front

What can make you think a stationary bus has started moving?

Back

A car in the next lane passes the bus.

Front

Which law is associated with the equation F = ma?

Back

Newton's second law of motion.

Front

What is the SI unit for distance?

Back

The SI unit for distance is the Meter.

Front

What does Newton's first law of motion state?

Back

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 is the formula for calculating weight?

Back

Weight = mass × gravity (W = mg).

Front

What is the difference between mass and weight?

Back

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

Front

What is inertia?

Back

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

Front

What is the SI unit for mass?

Back

The SI unit for mass is the Kilogram.
