Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its motion. It occurs when the total forces acting on an object are not equal, resulting in acceleration.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other. On Earth, it pulls everything toward the center of the planet, giving weight to objects.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It occurs when two surfaces rub against each other.

Front

What is a pendulum?

Back

A pendulum is a weight suspended from a fixed point that swings back and forth under the influence of gravity.

Front

What happens to objects when they are in motion?

Back

Objects in motion tend to stay in motion unless acted upon by an unbalanced force, according to Newton's First Law of Motion.

Front

What is the role of gravity on a ramp?

Back

Gravity pulls objects down the ramp, causing them to slide or roll.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces cause an object to accelerate.

Front

What is the effect of height on the distance an object travels down a ramp?

Back

Generally, a higher ramp allows an object to gain more speed due to gravity, potentially allowing it to travel further.

Front

What type of force is applied when pedaling a bike?

Back

When pedaling a bike, a push force is applied to the pedals, which moves the bike forward.

Front

What is the relationship between mass and inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. The greater the mass of an object, the greater its inertia.
