Forces

What is the physics term for a push or a pull?i

• accleration

• velocity

• speed

• force

When an object continues to move in the same direction at the same speed, we consider the object to have:

• balanced forces

• unbalanced forces

When an object changes it motion and starts to accelerate, we consider to the object to have:

• balanced forces

• unbalanced forces

Newton's first law tells us that an object that is at rest will remain at rest, and an object that is moving will continue to move in a straight line with CONSTANT SPEED, if and only if the net force acting on that object is:

• zero

• greater than zero

What is the net force acting on the object?

• 20 N Right

• 40 N Right

• 20 N Left

• 40 N Left

A box is being pushed by a person with 5 N of force to the right. The box has 5 N of friction force in the opposite direction. Will the box begin to move with this pushing force?

• Yes

• No

• Balanced
• Unbalanced

• Balanced
• Unbalanced

• Balanced
• Unbalanced

• Balanced
• Unbalanced
