Newtons laws of motion Flashcards
1
Q
motion
A
movement
2
Q
force
A
a push or a pull that alters or tends to alter the state of motion if a body
3
Q
how can a force make a body move - create motion
A
- force applied from face of a club head on a golf club onto the golf ball
- golf ball which was stationary is now moving
4
Q
A
5
Q
how can forces make a body slow down or stop
A
- force applied from hand brakes of a bike
- bike will slow down or stop (due to friction)
6
Q
how can forces make a body accelerate
A
- force from feet if runner to starting blocks
- 100 m sprinter pushes of blocks which causes acceleration
7
Q
how can forces make a body change direction
A
- force from hand of a volley baller to a volleyball
- volleyball moves in the direction opposite to the direction in which the volleyballer applied the force
8
Q
how can forces change the shape of a body
A
- force applied from foot to a football when kicking a ball
- ball changes shape
9
Q
Newton’s first law of motion is also known as the
A
law of inertia
10
Q
N1 - law of inertia
A
a body will remain at rest or uniform velocity until acted on by an external force
11
Q
inertia
A
- resistance of a body to change its state of motion
- (reluctance of a body to start/stop moving)
12
Q
velocity
A
rate of motion in a particular direction
13
Q
A
