Unit 2 - Motion Review #2

Front

What are the two factors affecting the magnitude of the force of gravity between two objects?

Back

Mass and distance.

Front

Which model has greater gravitational attraction: Model A or Model B?

Back

Model A.

Front

If Michael walked at 2 m/s for 3 minutes, how far did he walk?

Back

360 m.

Front

How do you find the net force when two forces are going in opposite directions?

Back

Subtract the smaller force from the larger force.

Front

What happens to the pull of gravity as the distance between two objects increases?

Back

The pull of gravity decreases.

Front

Define gravity.

Back

Gravity is the force that attracts two bodies toward each other, proportional to their masses and inversely proportional to the square of the distance between them.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma).

Front

What is net force?

Back

Net force is the total force acting on an object, taking into account all the individual forces acting on it.

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N).

Front

Explain the relationship between mass and gravitational force.

Back

The gravitational force increases with greater mass.
