StJ AQA Physics Year 10: Velocity Time Graphs. Lesson 4

The unit for acceleration is

• m/s

• m/s²

• m/s³

• d/t

1. Which of the following statements about speed and velocity is correct?

• Velocity only describes an object’s rate of motion.
• Speed describes how an object is changing its velocity.
• Speed and velocity both describe how an object is speeding up.
• Only velocity includes the direction an object is traveling.

Equation to calculate speed

• d = S/t

• S = m/s

• S = d/t

Equation to calculate acceleration?

• $a\ =\ \frac{\Delta v}{t}$

• $a\ =\ \frac{s}{t}$

• $a^2$

• $a\ =\ \Delta v\ x\ t$

How can we tell if an object is slowing down?

• The value calculated will be positive

• There will be 0 resultant force

• The value calculated will be negative

Which one of these is a scalar quantity?

• Displacement

• Distance

• Force

• Velocity

Velocity is both ____ and _____. 

• speed , direction 
• direction, mass
• volume, density 
• direction, magnitude 

What is the person doing from 5 seconds to 10 seconds?

• Walking 
• Running
• Standing Still 
• Walking Fast

According to the graph how far does the person travel in the first 5 seconds?

• 2 m
• 10 m
• 0 m
• 5 m
