FIZIX1st Sem Review - Forces

Front

What is mass?

Back

The amount of inertia an object has.

Front

What happens if the forces acting upon an object are balanced?

Back

The object must not be accelerating.

Front

Calculate the force applied to a 5 kg shopping cart if it accelerates at 3 m/s².

Back

15 N.

Front

What does it mean when it takes more force to accelerate an object with more mass?

Back

This best describes Newton's second law, the law of acceleration.

Front

Compare the force of a car on a bug to the force of the bug on the car when the bug splatters against the windshield.

Back

The forces are the same.

Front

What is Newton's first law?

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

Define inertia.

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma).

Front

What is acceleration?

Back

The rate of change of velocity of an object.

Front

What is Newton's third law?

Back

For every action, there is an equal and opposite reaction.
