# Lesson Worksheet: Mass, Speed, and Collisions Science

In this worksheet, we will practice describing how mass and speed affect collisions.

Q1:

True or False: Driving at fast speeds can cause forceful collisions.

• ATrue
• BFalse

Q2:

During a collision, a moving car with a small mass will cause a moving car with a bigger mass at the same speed.

• Aless damage than
• Bmore damage than
• Cthe same damage as
• Ddouble the damage of

Q3:

When the speed of an object increases, the kinetic energy of the object .

• Abecomes zero
• Bis not affected
• Cincreases
• Ddecreases

Q4:

True or False: In Newton’s cradle, the moving balls lose their kinetic energy in the form of heat and sound until they stop.

• ATrue
• BFalse

Q5:

Look at the table. Three toy cars of the same mass are on three ramps with different angles of inclination.

 Car The Angle of Inclination of the Road (A) (B) (C) Small Medium High

Which car has the highest speed? Why?

• ACar B, because as the inclination of the road increases, the speed decreases
• BCar C, because as the inclination of the road increases, the speed increases
• CCar C, because as the inclination of the road decreases, the speed increases
• DCar A, because as the inclination of the road decreases, the speed increases
