Year 10: Moving

A force is measured in ...

• Kilograms
• cm/m³
• Newtons
• Meters

A train travels at a speed of 18m/s. This is equivalent to the speed of:

• 5 km/h
• 64.8 km/h
• 68 800 km/h
• 0.005 km/h

In the image are a number of different forces. Identify which force is a non-contact force. 

• friction
• air resistance 
• thrust
• gravity

Newtons second law of motion relates the force exerted to the mass of a body and its acceleration
F=mass (kg) x acceleration (m/s²)
Use this law to calculate the following: 
A 1400kg car accelerates at 3m/s². What size force is needed to cause this acceleration?

• 4200 N
• 466.7 N
• 4200 kg
• 1397 kg

The position of a student is recorded over a 20 second interval by a motion sensor. Which of the following statements about the motion of the student is incorrect?

• The walker travels fastest between 10 and 15 seconds
• The walker travels at a constant speed while moving towards the motion sensor
• The average velocity for the whole walk is 0 m/s.
• The average speed for the whole walk is 0.3 m/s

A force is described as a ___________ or a ___________

• Pull, gravity
• Push , Pull
• Push, Friction
• Friction, Gravity

The picture of the position vs. time graph shows an object that is...

• accelerating/speeding up
• moving at a constant speed 
• not moving 
• accelerating/slowing down.
