Checkpoint 4 Review

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time. It is measured in meters per second squared (m/s²).

Front

How do you calculate acceleration?

Back

Acceleration can be calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What happens to the acceleration of two asteroids moving towards each other due to gravity?

Back

The acceleration will increase until the asteroids collide.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

What path does a package take when dropped from a moving plane?

Back

The package follows a parabolic path due to its horizontal motion (inertia) and vertical acceleration (gravity).

Front

True or False: Gravitational pull increases as you move further away from an object in space.

Back

False. Gravitational pull decreases as you move further away from an object.

Front

What remains constant for an object in free fall?

Back

The acceleration due to gravity remains constant at approximately 9.81 m/s².

Front

What is the formula for gravitational force?

Back

The gravitational force can be calculated using the formula: F = G * (m1 * m2) / r², where G is the gravitational constant, m1 and m2 are the masses, and r is the distance between the centers of the two masses.

Front

What is the difference between velocity and speed?

Back

Velocity is a vector quantity that includes both speed and direction, while speed is a scalar quantity that only measures how fast an object is moving.

Front

What is a parabolic trajectory?

Back

A parabolic trajectory is the curved path that an object follows when it is thrown or propelled near the Earth's surface, influenced by gravity.
