LC 1: Forces and Motion Review

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity. It can involve speeding up, slowing down, or changing direction.

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

What does velocity include that speed does not?

Back

Velocity includes both the speed of an object and the direction in which it is moving.

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

Motion is the change in position of an object over time.

Front

What is an example of constant speed?

Back

A car traveling at 60 kilometers per hour on a straight road without changing speed.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What does it mean if an object is in motion?

Back

An object is in motion if its position changes relative to a reference point over time.

Front

What is an example of negative acceleration?

Back

A car slowing down as it approaches a stop sign.

Front

What is the relationship between force and motion?

Back

A force applied to an object can cause it to start moving, stop moving, or change direction.
