Physical Science Unit 6 Review

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken. It is measured in meters per second (m/s).

Front

How do you calculate average speed?

Back

Average speed = Total distance / Total time.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. The greater the mass of an object, the greater its inertia.

Front

Which object has the greatest inertia: a 10.0 kg object at rest or a 5.0 kg object moving at 5.0 m/s?

Back

A 10.0 kg object at rest has less inertia than a 20.0 kg object at rest.

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as the mass of the object multiplied by the acceleration due to gravity (W = m * g).

Front

How do you calculate weight on a planet?

Back

Weight = mass * acceleration due to gravity (W = m * g).

Front

What is gravitational force?

Back

Gravitational force is the attraction between two masses, which increases with greater mass and decreases with greater distance.

Front

How does gravitational force change with mass?

Back

Gravitational force increases as the mass of an object increases.

Front

What is the formula for gravitational force?

Back

F = G * (m1 * m2) / r^2, where G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.

Front

What is relative velocity?

Back

Relative velocity is the velocity of an object as observed from a particular reference frame.
