Forces, Friction, & Gravity Review

Front

What is a force?

Back

A force is a push or pull acting upon an object, resulting from its interaction with another object.

Front

What is friction?

Back

Friction is the resistance that one surface or object encounters when moving over another.

Front

What is gravity?

Back

Gravity is the force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What does the length of an arrow in a force diagram represent?

Back

The length of the arrow represents the strength of the force.

Front

What does it mean for forces to be balanced?

Back

Forces are balanced when they are equal in size and opposite in direction, resulting in no change in motion.

Front

What does it mean for forces to be unbalanced?

Back

Forces are unbalanced when they are not equal, causing a change in motion.

Front

If a marble is rolling down a ramp and speeding up, what type of forces are acting on it?

Back

Unbalanced forces are acting on the marble.

Front

In a tug-of-war, if one group pulls with a greater force, what happens to the rope?

Back

The rope will move in the direction of the group applying the greater force.

Front

How do you calculate net force?

Back

Net force is calculated by adding all the forces acting on an object, taking into account their directions.

Front

What is the net force if a 10N force is applied to the right and a 5N force is applied to the left?

Back

The net force is 5N to the right.
