Force and Motion

Front

What is a reference point in motion?

Back

A reference point is a stationary object or location used to determine if another object is in motion.

Front

What can help alleviate motion sickness?

Back

Closing one's eyes can help reduce the symptoms of motion sickness.

Front

What is the force that pulls all objects toward each other?

Back

Gravity is the force that attracts all objects with mass toward one another.

Front

How does an increase in an object's mass affect its gravitational force?

Back

As an object's mass increases, the gravitational force it exerts also increases.

Front

What is relative motion?

Back

Relative motion is the change in position of one object compared to the position of another object.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is inertia?

Back

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

Front

What is the formula for calculating force?

Back

Force is calculated using the formula F = m * a, where F is force, m is mass, and a is acceleration.

Front

What is acceleration?

Back

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

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as weight = mass * gravity.
