Physical Science Physics Semester Review

Front

What occurs from point B to point C on a distance vs. time graph?

Back

Ashley stopped for 4 minutes.

Front

What does Newton's 1st law 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 gravitational force?

Back

The force of attraction between two masses, directed towards each other.

Front

What does a distance vs. time graph represent?

Back

It shows an object's speed.

Front

What is density?

Back

Density is the amount of mass in a given volume.

Front

What is Newton's 2nd law?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N).

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as Weight = Mass x Gravitational Acceleration.
