Force and Motion #4

Front

What is the relationship between force and motion?

Back

Force is a push or pull that can cause an object to accelerate, change direction, or change shape. The motion of an object is directly affected by the net force acting on it.

Front

How does mass affect the acceleration of an object when a force is applied?

Back

According to Newton's second law, acceleration is inversely proportional to mass. This means that for a given force, an object with a larger mass will accelerate less than an object with a smaller mass.

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = m * a, where F is force, m is mass, and a is acceleration.

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 net external force.

Front

What is the effect of friction on motion?

Back

Friction is a force that opposes the motion of an object. It can slow down or stop the movement of objects sliding against each other.

Front

What is the significance of a graph showing speed versus time?

Back

A speed versus time graph shows how the speed of an object changes over time. The slope of the graph represents acceleration.

Front

How does applying a greater force affect the speed of an object?

Back

Applying a greater force to an object will result in a greater acceleration, leading to an increase in the object's speed.

Front

What is the role of a pinball machine's plunger in terms of force?

Back

The plunger in a pinball machine applies a force to the ball, propelling it upward when the knob is pulled backward.

Front

What factors determine the winner in a race between two carts of equal mass?

Back

The winner in a race between two carts of equal mass is determined by the amount of force applied to each cart; the cart with the higher force will accelerate faster and win.

Front

What is a bar graph used for in experiments involving force and motion?

Back

A bar graph can visually represent the relationship between different forces applied and the resulting changes in speed or motion of objects.
