Answers
1
Potential energy is...
Light energy
Mechanical energy
Stored energy
Kinetic energy
2
Discontinuous
data is best plotted on a
Line graph because it looks nicer
Bar graph because it is easier
Bar graph so data can be separated into categories
Line graph because it is more accurate
3
What sort of energy is stored in a battery?
Electrical energy
Kinetic energy
Chemical energy
Heat energy
4
Net force is
The weight of a net
Thrust
The total force acting on an object
Weight
5
IN PHYSICS, inertia is...
slowness
the tendency of an object to resist changes in motion
a measure of mass
acceleration
6
If the dots on the ticker tape get further apart, the object attached to the ticker timer is...
Bouncing
Slowing down
Staying at the same speed
Speeding up
7
IN PHYSICS, gravity
Is the same as weight
Pulls objects towards the centre of the earth
Makes things go up
Is something very serious
8
In the experiment with the car loaded with weights, which variable was discontinuous?
The length of the string
The time taken to travel the distance
The speed of the car
The number of weights in the car
9
When there is no change in direction
Velocity is less than speed
Velocity is greater than speed
Velocity = acceleration
Velocity is the same as speed
10
Velocity is:
Time/distance
The same as acceleration
The same as speed
Similar to speed but with a direction
11
Newton's second law explains the relationship between force, mass and....
Acceleration
Inertia
Speed
Gravity
12
If there is no gravitational force, a body can have zero:
Mass
Molecules
Weight
Volume
13
A speed time graph can be used to determine
How far an object has travelled
All of the above
The time taken for an object to move a certain distance
Acceleration
14
The gravitational constant 'g' (9.8m/s
2
) is
acceleration
force
gravity
speed
15
Newton's third law states that for every action there is..
A consequence
An acceleration
An equal and opposite reaction
A motion
16
IN PHYSICS, force is
The same as acceleration
A push or a pull on an object
What gives a Jedi power
A group of soldiers
17
The reaction to your weight force when you sit on a chair is...
The chair pushing up on you
Friction between you and the chair
Your inertia
Gravity pushing you down
18
Acceleration is a measure of
How fast an object is moving
How much force is applied to an object
None of the above
How quickly an object's speed changes
19
Deceleration is
The same as acceleration
A made-up word
Going backwards
A decrease in speed
20
Newton's first law is also know as the law of....
Inertia
Motion
Acceleration
Unbalanced forces
21
In physics, speed is:
Distance travelled in a given time
Time taken to travel a certain distance
Of the essence
Distance travelled
22
When you stand on a set of scales, the number shown is actually
Your force
Your weight
Your mass
Your thrust
