Year 10 Physics 2

The metric unit for acceleration is ______.

• m
• m/s
• m/s²
• s

What is velocity?

• the quickness of an object
• the location of an object
• acceleration
• speed in a specific direction

Distance and Displacement are similar, but different. What is the key difference between the two?

• Distance is for year 8s and Displacement is for smart year 10s

• Distance provides the direction and the distance

• Displacement provides the direction and the distance

• Displacement provides direction and you have to calculate the distance to find it.

When converting from m/s to km/hr the conversion rate is..

• Multiply by 3.6

• Divide by 3.6

• Add 9.81

• Subtract 9.81

To calculate acceleration, you need to calculate the change in speed divided by the amount of time it took.

• True

• False

What are the units for velocity?

• m/s

• m

• s/m

• m/s/s

How many significant figures does 0.080 have?

Identify the two equations used to calculate average velocity?

• Average velocity = (u + v)/2

• V = s/t

• V = t/s

• a = (v-u)/t

Identify two equations that can be used to calculate a constant acceleration.

• a = (v-u)/t

• s/t = (u+v)/2

• v=s/t

• a= (v-u)/2

What motion might be described by this graph?

• It could be a ball thrown up into the air

• A ball is being held high in the air

• A ball is rolling down a hill

• A ball is not moving - it is stationary
