What is Newton's First Law

F=ma

Every action has an equal and opposite reaction

An object at rest stays at rest, an object in motion stays in motion. unless a resultant force acts on it

Friction

Which has more Inertia? (so need more force to move)

Truck

Ant

A cat

A skateboard

What is the net force?

20 N

0 N

400 N

40 N

what is the correct formula for force?

F=ma

$F=\frac{m}{a}$

$F=\frac{a}{m}$

$F=a\times v$

find the acceleration of the box.

12m/s² towards right

12m/s² towards left

40m/s²

60m/s

which of these is an effect of force?(tick mark the correct answers)

force can start a motion

force can stop a motion

force can change the direction of motion

force can change the shape of an object

force can change the speed a moving object

what is a force?

a push or a pull

change in displacement

change in direction

according to newtons first law, if the resultant force on an object is zero..... then

the object will stay at rest if was already at rest or

continue moving uniform velocity if was already moving

the object will accelerate

the object will slow down

the object will stop

force of gravity F_g on any object having mass "m kg" is given by......

F_g=m\times g

$F_g=\frac{m}{g}$

$F_g=\frac{g}{m}$

10.

A car is moving with a uniform speed that means....

all the forces acting on the car are balanced(Driving Force=Frictional force)

there is a resultant force acting on the car

the driving force is the resultant force acting on the car

11.

A car is accelerating in the direction of the driving force. This means....

the resultant force on the car is acting in the same direction as the driving force.

there is no resultant force on the car

the car will move with a constant speed

12.

Put the liquids in order from most dense to least dense?

4, 3, 2, 1

1, 2, 3, 4

3, 4, 2, 1,

4, 3, 1, 2

13.

Which liquid is the least dense?

oil

water

syrup

plastic bottle

14.

What is the formula for density?

density = mass x volume

density = mass / volume

density = mass + volume

density = mass - volume

15.

Frank has an eraser. It has a mass of 4g, and a volume of 2cm³. What is its density?

8 g/cm³

2 g/cm³

1/2 g/cm³

24 g/cm³

16.

What is the volume of Object X?

10.0 cm³

15.0 cm³

20.0 cm³

25.0 cm³

17.

Frank has a paper clip. It has a mass of 9g and a volume of 3cm³. What is its density?

3 g/cm³

1/3 g/cm³

27 g/cm³

39 g/cm³

18.

What is the formula for Mass?

Mass/Volume

Density x Volume

Mass/Density

19.

What is the formula for Volume?

Mass/Volume

Density x Volume

Mass/Density

20.

what is the value of acceleration due to gravity "g"?

10m/s²

20m/s²

25m/s²

8m/s²

21.

find the force of gravity on a box having mass 3kg

30N

30Kg

30m/s²

0.3N

22.

Newtons law states that for every action, there is an_________ reaction

unequal and opposite

stronger and opposite

equal and similar

equal and opposite

23.

What is the definition of "weight"?

measure of the force of gravity on your body

the time it takes to get on a ride

the amount of matter in an object

the size of an object

24.

A measure of how much matter an object has is--

weight

gravity

mass

volume

25.
