IPC 3rd six weeks test review

Front

What is the relationship between mass and acceleration?

Back

As mass increases, acceleration decreases.

Front

What is Newton's Third Law?

Back

For every action there is an equal and opposite reaction.

Front

What is an indicator of a chemical reaction?

Back

Change in color.

Front

What is the formula for momentum?

Back

Momentum = mass x velocity.

Front

Calculate the momentum of a 1000-kg car moving northward at 20 m/s.

Back

20000 kg * m/s north.

Front

What happens to the velocity of two objects that collide and stick together?

Back

They move at a combined velocity based on conservation of momentum.

Front

What is the formula for calculating acceleration?

Back

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

Front

Define inertia.

Back

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

Front

What does it mean for forces to be balanced?

Back

Balanced forces result in no change in motion.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).
