Year 10 Forces and acceleration

Velocity is ...

• Same as force

• Same acceleration

• speed with a direction

• same as force

The distance traveled by an object per unit time is called

• acceleration

• gravity

• force

• speed

Vectors are quantities that have magnitude and direction

• True

• False

Scalars are quantities that have a magnitude and direction

• True

• False

If the man pushes with an equal amount of force, which object will accelerate more?

• Car because it has more mass

• Lawnmower because it has less mass

• Car because it has less mass

• Lawnmower because it has more mass

If you increase the mass on an object, its acceleration

• decreases
• stays the same
• also increases
• stops

Something with a greater mass requires a(n) _____ force to move it. 

• greater
• lesser
• equal
• opposite

If you increase the force on an object, its acceleration

• decreases

• stops

• also increases

• stays the same

In equation form, Newton's Second Law of motion can be expressed as

• F=ma

• v=d/t

• a=v/t

• p=mv

According to Newton's second Law, which would take more force to slow down?

• The truck

• The car

• They would both take the same force

• Cannot be determined
