1Force is measured in [blank_start]Newtons (N)[blank_end]
Mass is measured in [blank_start]Kilograms (Kg)[blank_end]
Acceleration is measured in [blank_start]Meters per Second squared (m/s²)[blank_end]- ANewtons (N)
- BKilograms (Kg)
- CMeters per Second squared (m/s²)
2[blank_start]Friction[blank_end] is a force that opposes motion
- AFriction
3What is the equation to find force?
- Aa=mf
- Bm=a+f
- Cf=ma
- Da=m-f
4A balanced force makes a change in motion (net force)
- AVerdadeiro
- BFalso
5Tick all correct statements about unbalanced forces:
- AThe two forces cancel each other out
- BMakes a change in motion on an object
- CMake no net force
- DMakes an object move in the direction he larger force is pointing
6Two opposite forces are acting on an object, making the object accelerate. This is an example of [blank_start]an unbalanced[blank_end] force.
- Aan unbalanced
- Ba balanced
7Two opposite forces are acting on an object, but the object doesn't move. This is an example of [blank_start]a balanced[blank_end] force.
- Aa balanced
- Ban unbalanced
8Check all examples of non-contact forces:
- AFriction
- BGravity
- CTension
- DElectrostatic
- EMagnetism
9Friction can cause:
- Aheat
- Bacceleration (speeding up)
- Cacceleration (slowing down)
- Ddamage
10[blank_start]Iron[blank_end] is strongly magnetic
[blank_start]Nickel, chromium and cobalt[blank_end] are weakly magnetic
[blank_start]commercial magnets[blank_end] are an alloy of the two.- AIron
- BNickel, chromium and cobalt
- Ccommercial magnets
11If a magnet is cut in half, it ill still have a north and south end.
- AVerdadeiro
- BFalso
12Forces always act in pairs
- AVerdadeiro
- BFalso
13When falling, (e.g on earth due to gravity) mass does not effect acceleration. (Mass would effect how hard an object hits the ground, however).
- AVerdadeiro
- BFalso
14You jump out of a stationary helicopter. After 4 seconds, what will your acceleration be?
Answer: [blank_start]39.2[blank_end]m/s²- A39.2
15When you step on the scales, your mass is 45kg. What is your weight?
Answer: [blank_start]441[blank_end]N- A441
