1
Q
Linear motion
A
- Linear motion describes a one-dimensional motion along a straight line
- There are a number of forces that will act on an object or person during linear motion
2
Q
Gravity
A
- The force that attracts a body towards the centre of the Earth
3
Q
Static Frictional force
A
Static frictional force is the force exerted on one surface by another when there is no motion between the two surfaces
4
Q
Sliding frictional force
A
- Sliding frictional force is when dry friction acts between two surfaces that are moving relative to one another
5
Q
Air resistance
A
A force that acts in the opposite direction to the motion of a body moving through the air
6
Q
Internal Muscular Force
A
– Force generated by the skeletal muscles
7
Q
Weight
A
- The amount of gravity applied to mass
- Mass x acceleration
- measured in Newtons, N
8
Q
scalar quantity
A
- describes a magnitude, but not direction
9
Q
vector quantity
A
- describes a magnitude as well as a direction
10
Q
Velocity
A
- Measured in metres per second.
- This is how fast a body travels in a given direction
11
Q
Momentum
A
the product of the mass and velocity of an object
12
Q
Acceleration
A
- Measured in metres per second.
- This is the rate of change in velocity
13
Q
Displacement
A
- Measured in metres.
- This is the shortest route in a straight line between the starting and finishing positions
14
Q
Impulse
A
- Impulse is the time it takes for a force to be applied to an object or body
- Impulse (Ns) = force (N) x time (s)
