Motion and Acceleration review

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

What two measurements do you need to determine the speed of an object?

Back

Distance and time.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

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 motion?

Back

An object is in motion if it changes position relative to a reference point.

Front

What is a reference point?

Back

A reference point is a stationary object used to determine the position of another object.

Front

What is the unit of speed in the metric system?

Back

Meters per second (m/s).

Front

What is the significance of Earth's tectonic plates?

Back

Earth's tectonic plates are large sections of the Earth's outer layer that move and interact, causing earthquakes, volcanic activity, and the formation of mountains.

Front

How does friction affect motion?

Back

Friction is a force that opposes motion between two surfaces in contact, causing objects to slow down or stop.

Front

What is uniform motion?

Back

Uniform motion occurs when an object moves at a constant speed in a straight line.
