Topic 3 Lesson 1 Review

Front

What is the vertical speed of a parachutist when they open the parachute?

Back

The vertical speed is at point A on the graph.

Front

What type of force is tension?

Back

Tension is a Contact Force.

Front

During which segments of a speed vs. time graph are the forces acting on the object balanced?

Back

The forces are balanced during segments Q and S.

Front

What is the net force if the forces acting on an object are 11 N left and 0 N right?

Back

The net force is 11 N left.

Front

What is the net force if the forces acting on an object are 35 N right and 0 N left?

Back

The net force is 35 N right.

Front

Define net force.

Back

Net force is the overall force acting on an object after all the forces are combined.

Front

What happens to an object when the net force acting on it is zero?

Back

The object remains at rest or continues to move at a constant speed.

Front

What is a balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

Unbalanced forces cause an object to accelerate or change its motion.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, F = ma (Force equals mass times acceleration).
