Newton's Second Law

A change in velocity over time is called ___________.

• speed
• force
• acceleration
• direction

m/s² is the unit for.....

• Mass

• Force

• Acceleration

• weight

What Unit do we Measure Force in? 

• Newtons
• Joules
• Force
• Don't know

which box has more acceleration?

• top

• bottom

which box has more acceleration?

• top

• bottom

what happens to the acceleration when the force on an object is doubled?

• acceleration also doubles

• acceleration becomes half

• no change in the acceleration

• acceleration becomes zero

what happens to the acceleration of an object when the mass is halved? (force remains the same)

• acceleration doubles

• acceleration is also halves

• acceleration increases 4 times

• acceleration becomes zero

What do each of the letters correctly represent?

• Funny, Monkeys, Arrive
• Force, Mass, Acceleration
• Free, Mass, Access
• Force, Magnesium, Arsenic

what is the correct formula for force?

• F=ma

• $F=\frac{m}{a}$

• $F=\frac{a}{m}$

• $F=a\times v$

use the triangle to solve the question.
