Ocean Powered: Lesson 1 REVIEW

Front

If two forces (arrows) of the same length were pointing in the same direction on an object, would the object be moving or at rest?

Back

Moving, because the forces are unbalanced.

Front

What would happen if there were less wind acting on a turbine?

Back

The blades would move more slowly or stop.

Front

What happens to the motion of an object when the forces on it are balanced?

Back

The object's motion will be stable (the same).

Front

How does force affect the motion of an object?

Back

The stronger a force, the more motion it can create.

Front

How does an object’s mass affect its motion?

Back

Objects with more mass require more force to move them.

Front

What can you observe about the relationship between force and motion from the graph?

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

Back

The greater the force, the greater the acceleration.

Front

What can you observe about the relationship between mass and motion from the graph? Options:

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

Back

The greater the mass, the less the acceleration.

Front

When the ball begins to move, are the forces on it balanced or unbalanced?

Back

Unbalanced

Front

Which law is also known as the law of inertia?

Back

Newton's First Law

Front

What do Newton’s laws help us understand?

Back

The forces that push and pull everything
