Final Study Guide

Front

What is the unit for displacement?

Back

m (meters)

Front

How do you calculate acceleration?

Back

Acceleration = (Final Speed - Initial Speed) / Time

Front

What is the formula for calculating acceleration if an object changes speed?

Back

a = (v_f - v_i) / t, where v_f is final velocity, v_i is initial velocity, and t is time.

Front

What does gravity do?

Back

Gravity causes objects to pull towards one another.

Front

What is the acceleration of a roller coaster that goes from 6.0 m/s to 70 m/s in 4 seconds?

Back

16 m/s²

Front

What does a graph showing a horizontal line represent?

Back

An object at rest.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is the formula for calculating displacement?

Back

Displacement = Final Position - Initial Position.

Front

What is the significance of the slope in a distance-time graph?

Back

The slope represents the speed of the object.

Front

What is the effect of mass on gravitational force?

Back

The greater the mass of an object, the stronger the gravitational force it exerts.
