Forces Review

Front

What is gravity?

Back

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

Front

What happens to an object when a greater force is applied?

Back

When a greater force is applied to an object, it will accelerate more, meaning it will move faster or go higher depending on the context.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, caused by the contact between two surfaces.

Front

How does surface texture affect friction?

Back

Smoother surfaces have less friction, allowing objects to slide more easily, while rougher surfaces increase friction, making it harder for objects to move.

Front

What is the relationship between mass and gravitational force?

Back

The gravitational force between two objects increases with the mass of the objects; heavier objects exert a stronger gravitational pull.

Front

What is the effect of height on potential energy?

Back

The higher an object is positioned, the more potential energy it has due to its height in relation to the ground.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, which increases with the speed of the object.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is an example of a simple machine?

Back

A ramp is an example of a simple machine that helps lift objects by reducing the amount of force needed to raise them.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion; an object at rest stays at rest, and an object in motion stays in motion unless acted upon by a force.
