Friction, Gravity and Newton's Laws

Friction acts in this direction to the direction of an object's motion

• equal

• perpendicular

• opposite

Unless an object at rest is acted upon by a force, it stays at rest due to its

• matter

• friction

• inertia

The amount of matter in an object is it's

• inertia

• mass

• weight

Newton's first law of motion states:

• an object at rest stays at rest unless acted on by an outside force

• for every action there is an equal and opposite reaction

• force equals mass x accelleration

True or False: inertia is a force

• true

• false

The amount of the force of gravity acting on an object is the objects

• mass

• weight

• inertia

Newton's third law of motion states

• an object at rest will remain at rest unless acted on by an unbalanced force.

• for every action there is an equal and opposite reaction

• force equals mass x acceleration

The more mass an object has

• th easier it is to get moving

• the less force it needs to stop

• the harder it is to speed up

NGSS.MS-PS2-2

The more the force on an object

• the greater the speed

• the harder it is to change direction

• the harder it is to slow down

Tags

NGSS.MS-PS2-2

If an ojbect is moving and more force is applied

• it will keep going the same speed

• it will slow down and change direction

• it will speed up
