What is projectile motion?

Back

Projectile motion is when an object has both horizontal and vertical motion, typically following a curved path due to the influence of gravity.

Front

What is terminal velocity?

Back

Terminal velocity is the last speed a falling object reaches when the force of air resistance matches the force of gravity, causing the object to fall at a constant speed.

Front

What do we call an object that is in orbit?

Back

An object that is in orbit is called a satellite.

Front

What is the center of gravity?

Back

The center of gravity is the imaginary spot that shows where all the gravitational forces are balanced on an object.

Front

What is gravity?

Back

Gravity is the force of attraction between any two masses.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is free fall?

Back

Free fall is the motion of an object when it is falling solely under the influence of gravity, with no air resistance.

Front

What is the role of air resistance in falling objects?

Back

Air resistance opposes the motion of falling objects and can affect their speed and acceleration.

Front

What is the formula for calculating weight?

Back

Weight can be calculated using the formula: Weight = mass × gravity (W = m × g).

Front

What is a gravitational field?

Back

A gravitational field is a region of space around a mass where other masses experience a force of attraction.
