Unit Review - MS-PS2-2

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity, measured in meters per second squared (m/s²).

Front

What is force?

Back

Force is a push or pull on an object, measured in Newtons (N). It can cause an object to accelerate.

Front

What is Newton's First Law of Motion?

Back

Newton's First Law states that an object in motion will remain in motion unless acted upon by an outside force.

Front

What is net force?

Back

Net force is the total force acting on an object, taking into account all the individual forces acting on it.

Front

How do you calculate force?

Back

Force can be calculated using the formula: Force = Mass × Acceleration (F = m × a).

Front

If a car has a mass of 2000 kg and an acceleration of 5 m/s², what is the force acting on it?

Back

Force = 2000 kg × 5 m/s² = 10000 N.

Front

What happens to an object at constant velocity?

Back

An object at constant velocity has no net force acting on it; it continues to move at the same speed and in the same direction.

Front

What is the direction of net force when two forces act in opposite directions?

Back

The direction of the net force is towards the direction of the larger force.

Front

What is inertia?

Back

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