Front

What is the effect of gravity on released objects?

Back

Released objects always fall towards Earth’s surface.

Front

What happens to a stationary object when two equal forces act on it in opposite directions?

Back

The object will remain stationary.

Front

How does doubling Earth’s mass affect the gravitational force between Earth and the Sun?

Back

The gravitational force would increase.

Front

What does a graph showing positive acceleration indicate about the motion of an object?

Back

Segment OA and Segment DE show positive acceleration.

Front

What principle explains why a stuffed animal flies back when a car accelerates quickly?

Back

Inertia.

Front

Define gravity.

Back

Gravity is the force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What is inertia?

Back

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

Front

Explain the relationship between velocity and acceleration.

Back

Acceleration is the rate of change of velocity over time.

Front

What is the formula for calculating gravitational force?

Back

F = G * (m1 * m2) / r^2, where F is the gravitational force, 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 momentum?

Back

Momentum is the product of an object's mass and its velocity, represented as p = m * v.
