Forces

Which one is the horizontal component of this force?

Which one is the vertical component of this force?

Look at the diagram. What would be the direction of the motion ?

• movement to the left
• movement to the right
• no movement

These two chaps are moving this 200 kg box with a horizontal force of 600 N. What is the magnitude of the Normal Force?

• 5880 N

• 600 N

• 1960 N

• 61 N

• the less mass, the less acceleration

• the greater the force, the less acceleration

• is related to balance

• the greater the mass, the less acceleration

The Normal is a force that:

• Never produces acceleration

• Has the direction of motion

• Is equal to the inertia

• Occurs in free fall

The friction force:

• Never produces acceleration

• It's perpendicular to the surface

• Is not related to non-equilibrium

• It is always opposite to the movement

According to Newton's 2nd Law, when an object is thrown upward:

• It has no acceleration

• its acceleration goes downwards

• its acceleration is zero at the highest point

• while it rises it is in balance

The greater the mass and the less force, the greater the acceleration.

• True

• False

If the force acting on an accelerating body is doubled, its acceleration is also doubled.

• True

• False
