ULTIMATE SCIENCE! (Exam Prep) 8th

The rate that describes how far an object moves over time is 

• Acceleration

• Speed

• Force

• Velocity

Acceleration includes the following

• Increasing speed

• Decreasing speed

• Change in Direction

• All of the Above

Limitations on an engineering solution are known as

• Criteria

• Constraints

• Integrations

• Innovations

A car begins at 12 m/s and then speeds up to 36 m/s in 6 seconds. Calculate the average acceleration

• 2 m/s^2

• 4 m/s^2

• 8 m/s^2

• 12 m/s^2

An object’s speed and direction of motion is

• Acceleration

• Force

• Velocity

• Speed

A unit used to measure the strength of a force:

• Kilograms (kg)

• Seconds (s)

• Mass (m)

• Newtons (N)

A push or a pull on an object is known as:

• Acceleration

• Force Pairs

• Force

• Gravity

What is the equation for force?

• Force = mass x distance

• Force = mass x altitude

• Force = mass x acceleration

• Force = distance x acceleration

What is the value for acceleration due to gravity on Earth?

• 98.2 m/s^2

• 9.8 m/s^2

• 1.98 m/s^2

• 0.198 m/s^2

A box weights a total of 20 kg. How much force would be required in order to lift the box?

• 196 N

• 67 N

• 196 kg

• 67 kg
