1
What is the correct equation for Kinetic energy?
K.E = momentum
K.E =Distance / Time
K.E = 0.5mv2
k.E = 0.5ma
2
The graph details the trip of a car? What is the Velocity of the car at 20 seconds?
1.5 m/s
1.0 m/s
2.0 m/s
0.5 m/s
3
An object with unbalances forces acting on it, will...
Stay at rest
Dance the night away
Not move
Move
4
The tendency of an object to stay at rest is called
Torque
Motion
Friction
Inertia
5
What is the correct equation to get the Speed of an object?
Speed = Distance xTime
Speed = Acceleration/Velocity
Speed = Force / Time
Speed = Distance / Time
6
This man moves with a velocity of 5 m/s. What is his momentum? (NOTE: P= mxv)
300 kg m/s
350 kg m/s
320 m/s
300 N
7
What is the speed of a Zonkey moving 100 m in 360 sec?
5 m/s
3.0 km/s
20 m/h
0.27 m/s
8
Calculate the momentum of the van before collision. (NOTE: P = m x v)
12,000 kg/s
16,000 kg m/s
12,600 kg m/s
1650 kg m/s
9
What is the speed of a car traveling 600 meters in 1 minute?
40 m/s
60 m/s
10 m/s
10 N
10
Work done = Force x Distance. Rearrange this to calculate Force
Force = Distance / Time
Force = mass x work done
Force = Workdone / Distance
Force = Velocity
11
An object with balanced forces acting on it will...
Will accelerate
Slow down it's motion
Not change its motion
Change Direction
12
Velocity will tell you how fast an object is moving over a period of time , also it's
Direction
Acceleration
Motion
Rest
13
Cindy ran from rest and achieved a velocity of 3m/s after 10 sec. What is her initial velocity?
3 m/s
1.5 m/s
0 m/s
1 m/s
14
I will need a greater force to move an object with more ___________________
Mass
Motion
Resultant Force
Speed
15
What is motion?
An object not moving because of the unbalance forces
No movement
Change of position over time
Stationary object
16
What equation should be use when you are looking for a distance traveled by an object?
Force = mass x Acceleration
Time = Distance - Speed
Speed = Distance/T
Distance = Speed x Time
17
The graph details the trip of a car? How far has it travelled after 30 sec?
20 metres
10 meters
15 meters
17 minutes
18
Using the distance traveled over time graph, find the average speed of the runner
10 m/s
4 m/s
40 m/s
8 m/s
